One of the most frequent complaints of pet parents is that their dogs “just won’t listen.” But put yourself in your dog’s shoes for a moment. If someone was constantly chattering away in a foreign language that you’d never heard before, how long would you pay attention? Probably not for very long-because you simply wouldn’t be able to understand what the foreign speaker was trying to communicate.

This training collar actually uses one of the most popular and effective forms of correction; citronella spray. What this means is that when the dog barks, the microphone in the box on the collar will be activated; releasing a burst of harmless citronella into the room. Dogs are not too fond of this odour, and they will associate barking with the smell. 

The oldest form is a “shock” collar, but a lot has changed since then; they’re no longer painful and inhumane; even the Humane society supports its use (for modern collars, that is). There are other forms of stimulus that will deter dogs, too, though. You can try a collar that spurts an unpleasant smell (usually citronella as dog’s don’t care for that) when your dog is misbehaving. Other stimuli include loud sounds, ultra-sonic sounds, lights, and vibrations.
When teaching new skills, keep training sessions short and sweet Like kids, dogs don’t have long attention spans. There’s no hard-and-fast rule, but an ideal average training session should last 15 minutes or less. Within that session, you can work on one skill or switch between a few different skills. To keep things interesting, try doing 5 to 15 repetitions of one behavior and then doing 5 to 15 repetitions of another behavior. You can also practice new skills and keep old ones polished by doing single repetitions at convenient times throughout the day. For example, before giving your dog a tasty new chew bone, ask her to sit or lie down to earn it. go here for more
You may also notice common behavior problems in your dog such as jumping up, barking, or even aggression. The best way to correct any misbehavior is to interrupt it. Shift your dog's attention to something positive. Try running through cues that your dog has mastered followed by rewards. Keep your demeanor cool and confident, and be clear about what you mean.
From a young age, dogs engage in play with one another. Dog play is made up primarily of mock fights. It is believed that this behavior, which is most common in puppies, is training for important behaviors later in life. Play between puppies is not necessarily a 50:50 symmetry of dominant and submissive roles between the individuals; dogs who engage in greater rates of dominant behaviors (e.g. chasing, forcing partners down) at later ages also initiate play at higher rates. This could imply that winning during play becomes more important as puppies mature.[11]
Just like people, every dog is different. The breed and the way you raise them are certainly factors, but sometimes their individual personality is the biggest determiner when it comes to the ease of training. You may have been able train one dog without any aides at all but still find yourself scratching your head on getting your next dog to behave. For those more stubborn dogs (or if you simply can’t devote the same amount of time to your new dog), they have dog training collars that can help you.

The term personality has been applied to human research, whereas the term temperament has been mostly used for animal research.[18] However, both terms have been used interchangeably in the literature, or purely to distinguish humans from animals and avoid anthropomorphism.[19] Personality can be defined as “a set of behaviors that are consistent over context and time”.[20] Studies of dogs' personalities have tried to identify the presence of broad personality traits that are stable and consistent over time.[19][20][21][22] how to potty train a puppy
If you’d like to learn how to train your dog or if your dog has a behavior problem you’d like to resolve, don’t hesitate get help from a qualified professional trainer or behaviorist. To learn more about locating the right expert for you and your dog, please see our article, Finding Professional Help. Many Certified Pet Dog Trainers (CPDTs) and Certified Applied Animal Behaviorists (CAABs or ACAABs) offer telephone consultations, in-home private consultations and training sessions, and group classes.
Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors.[57][58] In 2016, a study found that there were only 11 fixed genes that showed variation between wolves and dogs. These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response[58][59] (i.e. selection for tameness), and emotional processing.[58] Dogs generally show reduced fear and aggression compared to wolves.[58][60] Some of these genes have been associated with aggression in some dog breeds, indicating their importance in both the initial domestication and then later in breed formation.[58]
Step 1: Using either a laser pointer or touch stick, get your dog in the habit of jumping up to touch the light switch. It is best to have him jump up with his pads on the wall (instead of his claws) touching the switch with his nose. I used a laser pointer here, because I would play with it as a game, knowing that he would really go after it—even if it's on a wall.
Crate training is a great way to start your puppy off on the right paw. Dogs have a natural instinct to keep their den clean, so a properly sized crate, introduced gradually, will create a home base for your puppy and will keep him from having accidents when you can’t watch him. Use the crate when you’re unable to give your puppy your full attention during the day, as well as at nap time and bedtime. Selecting the right size crate is critical, and it should be big enough so that your puppy can comfortably stand up, turn around and lie down but not much bigger. If you opt for a crate that’s too large, your puppy will be able to potty in one corner and sleep comfortably in the other, defeating the purpose of crate training.
Dogs differ from wolves and most other large canid species as they generally do not regurgitate food for their young, nor the young of other dogs in the same territory.[78] However, this difference was not observed in all domestic dogs. Regurgitating of food by the females for the young, as well as care for the young by the males, has been observed in domestic dogs, dingos and in feral or semi-feral dogs. In one study of a group of free-ranging dogs, for the first 2 weeks immediately after parturition the lactating females were observed to be more aggressive to protect the pups. The male parents were in contact with the litters as ‘guard’ dogs for the first 6–8 weeks of the litters’ life. In absence of the mothers, they were observed to prevent the approach of strangers by vocalizations or even by physical attacks. Moreover, one male fed the litter by regurgitation showing the existence of paternal care in some free-roaming dogs.[79] more on this
Sometimes, our dogs just don’t seem to respond to us when we try to train them. They may be stubborn, strong-willed, or just a little mischievous. Of course, there are some habits that need to be broken for their safety as well as our own - or just because the neighbours are starting to complain about your dog’s barking and you don’t want to get fined. 

Loud sound/ultra sonic. This deterrent will set off a loud sound or an ultra sonic tone that will surprise your dog when he’s caught being a bad dog. If reviews are to be believed, this is the least effective of the most commonly used deterrents but it’s also the nicest, so if you’re feeling guilty this may be your solution. Often a beep is combined with another type of deterrent and that seems to be more effective, though.

Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli.[1] It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned in these fellow mammals.[2] Behavioral scientists have uncovered a wide range of social-cognitive abilities in the domestic dog.
Dogs have an olfactory sense 40 times more sensitive than a human's and they commence their lives operating almost exclusively on smell and touch.[6]:247 The special scents that dogs use for communication are called pheromones. Different hormones are secreted when a dog is angry, fearful or confident, and some chemical signatures identify the sex and age of the dog, and if a female is in the estrus cycle, pregnant or recently given birth. Many of the pheromone chemicals can be found dissolved in a dog's urine, and sniffing where another dog has urinated gives the dog a great deal of information about that dog.[6]:250 Male dogs prefer to mark vertical surfaces and having the scent higher allows the air to carry it farther. The height of the marking tells other dogs about the size of the dog, as among canines size is an important factor in dominance.[6]:251
Inappropriate urination and defecation are among the most frustrating dog behaviors. They can damage areas of your home and make your dog unwelcome in public places or at the homes of others. It is most important that you discuss this behavior with your veterinarian first to rule out health problems. If no medical cause is found, try to determine the reason for the behavior, which can come down to one of the following:
Introduce your new pup to its new home, family and their role. Just like when you are new to a place or group, your new pet may be bursting with curiosity, excitement, fear or joy. Now is the best time to lay out the foundation for a good and pleasant relationship with your pet. For a puppy to settle in and learn to trust and respect you and everyone at home, it is very important to establish your expectations of your puppy and be consistent with them.
You should always accompany your puppy outside for potty breaks. You’re there not only to ensure that he actually goes, you’re also there to reward your puppy with a treat for going in the proper spot. Wait until your puppy finishes eliminating and immediately give him a tasty reward for a job well done. If you wait until you get back in the house, your puppy won’t make the connection between his elimination and the reward. go here for more

Give your dog the cue to go potty as soon as you reach her potty spot. If she goes, give her lots of verbal praise and a treat. If more than a minute passes without any indication that she is about to go potty, then leave the potty place and return in a few minutes to try again. If you are training indoors, it is best to go to another room. If you are training outdoors, you should go back inside before returning.
In the UK between 2005 and 2013, there were 17 fatal dog attacks. In 2007–08, there were 4,611 hospital admissions due to dog attacks, which increased to 5,221 in 2008–09. It was estimated in 2013 that more than 200,000 people a year are bitten by dogs in England, with the annual cost to the National Health Service of treating injuries about £3 million.[97] A report published in 2014 stated there were 6,743 hospital admissions specifically caused by dog bites, a 5.8% increase from the 6,372 admissions in the previous 12 months.[98] dog training tips
Do not scold your dog harshly if you catch him urinating in the wrong place. Calmly say, "No," and bring him to his potty place with a piece of soiled paper towel. Only scold your dog for going in the wrong place if you catch her in the act. Do not drag her back to a puddle to scold her. She will not understand that it is the location of the urine that is the problem and may even begin to fear urinating in front of you. Puppy potty Training

If you watch two dogs playing together, you will frequently see them bow. Trainers refer to this behavior as a play bow, and it is a dog's way of asking another dog to come and play. You can easily use your dog's natural playfulness to train it to take a bow. And it's a great way to end a demonstration of all the cool new dog tricks your dog has learned! Puppy Training

In 2004, a study reviewed 5 other studies of feral dogs published between 1975 and 1995 and concluded that their pack structure is very loose and rarely involves any cooperative behavior, either in raising young or in obtaining food.[82] Feral dogs are primarily scavengers, with studies showing that unlike their wild cousins, they are poor ungulate hunters, having little effect on wildlife populations where they are sympatric.[83]:267 However, several garbage dumps located within the feral dog's home range are important for their survival.[84] Even well-fed domestic dogs are prone to scavenge; gastro-intestinal veterinary visits increase during warmer weather as dogs are prone to eat decaying material.[85] Some dogs consume feces, which may contain nutrition.[86][87] On occasion well-fed dogs have been known to scavenge their owners' corpses.[88] Puppy potty Training
The motivation for a dog to play with another dog is distinct from that of a dog playing with a human. Dogs walked together with opportunities to play with one another, play with their owners with the same frequency as dogs being walked alone. Dogs in households with two or more dogs play more often with their owners than dogs in households with a single dog, indicating the motivation to play with other dogs does not substitute for the motivation to play with humans.[13] Puppy Training

Training collars typically use vibrations or static simulation (or a mild electric shock) to foster obedience, whether you’re trying to stop an aggressive behavior or teach your dog to walk with a leash. While many of these products can be expensive, this one from Mockins checks all the major boxes and comes at a low cost. Fitting dogs 15 pounds or larger, it offers 100 levels of vibration and static shock, with the delivery preceded by a warning tone. It’s also waterproof and fully rechargeable. Dog Training
The “shock factor” of many training collars doesn't appeal to everyone. That’s understandable—and there are other options for pet owners who want to promote better behavior, but are worried about causing their dog pain. This collar from Wolfwill exclusively uses tones and vibration to give your dog feedback and is still highly effective. The vibration feature has 16 levels of intensity, and the collar works at a range of up to 660 yards. The transmitter is designed with touch-distinguished buttons made with blind users in mind, but the product isn’t specific to owners of seeing-eye dogs.
When you have to leave the puppy alone, you’ll need to confine it to a crate. This will prevent the puppy from peeing and pooping all over your home, and will also help teach it control, since it won’t want to soil the crate. However, young puppies need frequent bathroom breaks, so you’ll also need to ask a friend or pet-sitter to stop by and let the puppy out throughout the day until it’s old enough to go for longer stretches without needing to use the bathroom. go here for more

If your dog is house trained, it may come as a surprise if you see him urinating in your home. Dog behavior doesn't usually change without reason. Formerly reliable dogs who suddenly begin urinating inside need your attention! This is a sign that something may be very wrong with your furry friend, and when he relieves himself frequently–even if he is in the correct location–it can be a sign of a urinary tract, bladder, or kidney infection. In an older dog, it may even be a sign of dementia. dog training collar
Step 1: Have your dog lay down. Wait for him to stand up. When he stands up, click and treat. Repeat this action several times until he learns that he has to stand up in order to get his treat. Standing is so natural that it is likely that the dog won't immediately understand why he is being rewarded, so it may take more repetition than usual. (Initially, it's okay to click even if.............................................

Service dogs are those that are trained to help people with disabilities such as blindness, epilepsy, diabetes and autism. Detection dogs are trained to using their sense of smell to detect substances such as explosives, illegal drugs, wildlife scat, or blood. In science, dogs have helped humans understand about the conditioned reflex. Attack dogs, dogs that have been trained to attack on command, are employed in security, police, and military roles. Service dog programs have been established to help individuals suffering from Post Traumatic Stress Disorder (PTSD) and have shown to have positive results [96]

Martingale collars are the humane successor to the choke chains of old. They operate in a similar fashion, with the collar tightening when your dog starts to pull. But because of the limited closure, it’s much safer and won’t actually choke your dog—just adjust to the size of their neck. For that reason, it’s also a great choice for pet owners whose dogs have a habit of slipping out of their leash.


The remote will actually let you train two dogs at once thanks to its dual functionality, all you need is an extra collar. There are 100 vibration levels, and you can choose whether to solely use vibration or sound, as well as both. The collar is also a one size fits all, so you shouldn’t have any trouble adjusting it to your dog. Completely waterproof and with rechargeable batteries, it was built to last.  how to potty train a puppy
Yes, a training collar is completely safe for your dog. This is because they only use sound, vibration, or citronella spray. Each of these is completely harmless and designed to give your dog a surprise as opposed to an electric shock. They are effective for training, and they will not cause increased aggression because your dog is not feeling any pain, they are just a little startled by the sudden sound, sensation, or smell. 

There is only one acceptable methodology for potty training a dog of any age: positive reinforcement. Traditional advice suggested swatting a dog or rubbing his face in his waste for mistakes in the house, but those techniques do nothing to make the potty training process more understandable for your dog and can actually damage your relationship with him. Keep in mind, dogs don’t view their waste the way we do – to them, pee and poo is pretty interesting! Punishing your dog for going in the house won’t help him understand what he should do instead and might make him afraid to go near you at all, inside or out. Successful potty training requires patience, kindness and remembering that your new puppy is just learning the rules. Dog Training
Here’s a good one to round out a demonstration of your dogs’ best tricks: send her to bed for a good rest after all that hard work! “Go to bed” is useful as a cue when your dog needs to be removed from the action and settle down. Of course, you can always take it to the next level by training her to pull the covers over herself…but that one might take a little more time.

In 1982, a study to observe the differences between dogs and wolves raised in similar conditions took place. The dog puppies preferred larger amounts of sleep at the beginning of their lives, while the wolf puppies were much more active. The dog puppies also preferred the company of humans, rather than their canine foster mother, though the wolf puppies were the exact opposite, spending more time with their foster mother. The dogs also showed a greater interest in the food given to them and paid little attention to their surroundings, while the wolf puppies found their surroundings to be much more intriguing than their food or food bowl. The wolf puppies were observed taking part in antagonistic play at a younger age, while the dog puppies did not display dominant/submissive roles until they were much older. The wolf puppies were rarely seen as being aggressive to each other or towards the other canines. On the other hand, the dog puppies were much more aggressive to each other and other canines, often seen full-on attacking their foster mother or one another.[64]
Just as a growing child, your dog will want to chew on toys and other objects to relieve the pain of a new set of teeth coming in. If your dog is full grown, you may also come home to find your couch cushions or favorite pair of shoes ripped to shreds, but it is not because they enjoy the taste. Your dog could be exhibiting signs of separation anxiety or anxiety in general. See 5 steps to correct inappropriate dog chewing.
Despite claims that dogs show more human-like social cognition than wolves,[65][66][67] several recent studies have demonstrated that if wolves are properly socialized to humans and have the opportunity to interact with humans regularly, then they too can succeed on some human-guided cognitive tasks,[68][69][70][71][72] in some cases out-performing dogs at an individual level.[73] Similar to dogs, wolves can also follow more complex point types made with body parts other than the human arm and hand (e.g. elbow, knee, foot).[72] Both dogs and wolves have the cognitive capacity for prosocial behavior toward humans; however it is not guaranteed. For canids to perform well on traditional human-guided tasks (e.g. following the human point) both relevant lifetime experiences with humans - including socialization to humans during the critical period for social development - and opportunities to associate human body parts with certain outcomes (such as food being provided by human hands, a human throwing or kicking a ball, etc.) are required.[74] go here for more
Seeking professional help doesn't mean ditching your DIY training program. You can find a professional dog trainer who offers private training sessions, and some trainers even offer online sessions. Many dog owners prefer to join a local dog obedience class so they will be under the supervision of a dog training instructor without the higher cost of private sessions. Plus, classes challenge your dog to learn around the distractions of other dogs.

Approach accidents in the right way. When this happens, do not punish your pup. Instead, when you catch him eliminating in the house, clap loudly to let him know he’s done something inappropriate. Then, immediately take him outside by calling his name or leading him gently by the collar. When he finishes eliminating outside, respond by giving him praise and/or a small treat to reinforce the behavior. Puppy potty Training

Dog communication is about how dogs "speak" to each other, how they understand messages that humans send to them, and how humans can translate the ideas that dogs are trying to transmit.[6]:xii These communication behaviors include eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs) and gustatory communication (scents, pheromones and taste). Humans communicate with dogs by using vocalization, hand signals, and body posture. Dogs can also learn to understand communication of emotions with humans by reading human facial expressions.[7]
With your dog sitting at your side, set off and give the command “heel” (so that your dog is aware you are about to move). If the dog gets ahead, stop and encourage it back to your side with a titbit. Repeat. To begin with, stop every three to four paces to praise your dog and give a titbit. Do not use your voice unless your dog is at your side. You can also practise this off-lead in a secure area – this makes you work really hard at keeping your dog with you, rather than relying on the lead. Puppy Training

Dogs (and wolves) mark their territories with urine and their stools.[37] The anal gland of canines give a particular signature to fecal deposits and identifies the marker as well as the place where the dung is left. Dogs are very particular about these landmarks, and engage in what is to humans a meaningless and complex ritual before defecating. Most dogs start with a careful bout of sniffing of a location, perhaps to erect an exact line or boundary between their territory and another dog's territory. This behavior may also involve a small degree of elevation, such as a rock or fallen branch, to aid scent dispersal. Scratching the ground after defecating is a visual sign pointing to the scent marking. The freshness of the scent gives visitors some idea of the current status of a piece of territory and if it is used frequently. Regions under dispute, or used by different animals at different times, may lead to marking battles with every scent marked-over by a new competitor.[6]:252–4 more on this
