When looking for a dog it’s important to understand breed traits. Whether you choose a purebred puppy from a breeder or a mixed breed from a shelter, all dogs will have certain behaviors based on their breeding.
This means that even though you may want a cute and fuzzy sheepdog as your fellow couch potato, that sheepdog needs some time to run every day. If dogs are not able to be exercised in a way that matches their traits, most dogs will become bored and possible destructive.
