The process is the exactly same for older dogs as it is for puppies; prevent accidents from happening by using baby gates and a crate if possible, create a predictable schedule, learn to recognize your dog’s potty signals, accompany your dog outside and immediately reward for all outdoor elimination, properly clean any accidents and supervise your dog until you’re sure that he understands the rules.
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
Dog behavior problems are often misunderstood or mishandled by dog owners. Perhaps you are new to dog ownership, considering getting a dog, or just wish to help your dog with a challenging issue. Thoroughly understanding the most common dog behavior problems is the first step to solving and preventing them. A solid foundation of obedience training will help you prevent or better control many of these issues. Dog Training
Domestic dogs appear to pay little attention to relative size, despite the large weight differences between the largest and smallest individuals; for example, size was not a predictor of the outcome of encounters between dogs meeting while being exercised by their owners nor was size correlated with neutered male dogs.[36] Therefore, many dogs do not appear to pay much attention to the actual fighting ability of their opponent, presumably allowing differences in motivation (how much the dog values the resource) and perceived motivation (what the behavior of the other dog signifies about the likelihood that it will escalate) to play a much greater role.[34] dog training classes

For dogs, English is a second language Dogs aren’t born understanding English. They can learn the significance of specific words, like “sit” and “walk” and “treat,” but when humans bury those familiar words in complex sentences, dogs sometimes have difficulty understanding. They can also get confused when people use different words for the same thing. For example, some people will confuse their dogs by saying, “Fluffy, down!” one day and “Sit down, Fluffy!” another day. Then they wonder why Fluffy doesn’t respond the same way every time. When teaching your dog a cue or command, decide on just one word or phrase, and make sure you and your family use it clearly and consistently. more on this

At this initial stage, we teach the dog how to learn from and interact with the handler. This establishes a bond essential for reducing stress and increasing opportunities for fun.We use food rewards to shape and lure the dog into foundation positions. Repetition is key to the dog’s learning. Once the dog is offering the behaviours freely, a ‘cue’ word is added.All work happens in our training barn, where outside distractions are minimised. dog training collar
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] go here for more
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]
Taking the learning from Stages 1 and 2, we now test the dog within a public environment with real life distractions. This period can be the most challenging for the dog. Using a range of public locations we train the dog to utilise learned behaviours.During Stage 3 we expect the dog to work on verbal commands only, asking for a higher level of obedience. The training is still fun. At this stage, we have usually exchanged the food reward for a toy.
Yes – with a warning. Most bark collars respond to a bark with a negative stimulus: citronella spray, ultrasonic sound, or a brief shock. The problem, and the warning, is for homes with multiple dogs or even dogs nearby. For this reason, many bark collars come with adjustable levels of sensitivity, making it harder to set off or easier, depending on your specific situation. You don’t want your dog getting negative reinforcement when another dog is misbehaving; of course because it’s cruel but also because it will confuse him and make the collar worthless. So use these collars carefully and never when he’s in the company of other untrained dogs. dog training classes
