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]
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
Take baby steps Dogs, just like people, learn best when new tasks are broken down into small steps. For example, you can’t go out and line dance unless you learn all of the individual steps first! When teaching your dog a new skill, begin with an easy first step and increase difficulty gradually. If you’re training your dog to stay, start by asking her to stay for just 3 seconds. After some practice, try increasing the duration of her stay to 8 seconds. When your dog has mastered an 8-second stay, make things a little harder by increasing the time to 15 seconds. Over the next week or two, continue to gradually increase the duration of the stay from 15 seconds to 30 seconds to a minute to a few minutes, etc. By training systematically and increasing difficulty slowly, you’ll help your dog learn faster in the long run. how to potty train a puppy

Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:

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. how to potty train a puppy
