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]
There are several medical issues that can interfere with potty training. Dogs with a urinary tract infection (UTI) will urinate frequently in small amounts, and will not have much control. You may also notice excessive licking of their genital region. If you notice a change in the consistency of their stool, the cause could be a gastrointestinal issue. Some common causes in puppies are intestinal parasites, having eaten something not in their normal diet, or a sudden food change. If a food change is necessary, do it gradually over 5 to 7 days. If you suspect any of these issues could be a problem, you should consult with your veterinarian.[19]

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.

Female dogs have an estrous cycle that is nonseasonal and monestrus, i.e. there is only one estrus per estrous cycle. The interval between one estrus and another is, on average, seven months, however, this may range between 4 and 12 months. This interestrous period is not influenced by the photoperiod or pregnancy. The average duration of estrus is 9 days with spontaneous ovulation usually about 3 days after the onset of estrus.[44]
If you run into trouble, go back a few steps If you’re training your dog to do something new and you stop making progress, you may have increased the difficulty of the skill too quickly. Similarly, if you’re practicing a behavior your dog hasn’t performed in a while and she seems a little rusty, she may need some help remembering what you want her to do. If you run into training challenges like these, just refresh your dog’s memory by making the skill a little easier for a few repetitions. Go back to a step that you know your dog can successfully perform, and practice that for a while before trying to increase difficulty again.
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.
Consideration: Many little dogs generally don’t like to rock the boat. This is especially true if they’ve been punished for accidents. A lot of people think punishing works because their dog or pup looks guilty. Well, that guilty look is just fear. And it doesn’t work; why else would you be reading this article? Often a little dog will make it easy on everyone and potty in a remote corner of the house. Think back: was there a time your puppy nipped, barked, or jumped at you repeatedly? Don’t ignore it—that’s the doggy equivalent of a toddler’s crotch grasping or body squirm. Our dog will nip, jump, and bark at you to tell you he’s gotta go!
This is one of the cheapest training collars you will find, which makes it perfect if you are on a budget and looking to save money. While the absence of the power switch can be irksome, the recharge time is not particularly long so you don’t need to wait for ages to be able to use it again. Using safe and cruelty-free methods, this is a fantastic choice if you are looking to stop excessive barking in your dog.
Waterproof. There are varying degrees of waterproof and you may opt not to get the 100% water proof version but we highly recommend having some water resistance for a dog training collar. There are simply too many actions dogs commonly take that accidentally get water on them. They could run in the rain before you get them in or they could splash through a mud puddle. Just the act of drinking their water could slop water up onto their collar without any real surprise to a pet parent. Take some precautions to prevent ruining the collar you choose. dog training tips
Resource guarding is exhibited by many canines, and is one of the most commonly reported behaviour issues to canine professionals.[50] It is seen when a dog uses specific behaviour patterns so that they can control access to an item, and the patterns are flexible when people are around.[51] If a canine places value on some resource (i.e. food, toys, etc.) they may attempt to guard it from other animals as well as people, which leads to behavioural problems if not treated. The guarding can show in many different ways from rapid ingestion of food to using the body to shield items. It manifests as aggressive behaviour including, but not limited to, growling, barking, or snapping. Some dogs will also resource guard their owners and can become aggressive if the behaviour is allowed to continue. Owners must learn to interpret their dog's body language in order to try to judge the dog's reaction, as visual signals are used (i.e. changes in body posture, facial expression, etc.) to communicate feeling and response.[50] These behaviours are commonly seen in shelter animals, most likely due to insecurities caused by a poor environment. Resource guarding is a concern since it can lead to aggression, but research has found that aggression over guarding can be contained by teaching the dog to drop the item they are guarding.[51] go here for more
