We often hear statistics cited that indicate dogs in the U. are seriously overweightS One of the reasons is due to the fact that most dogs don’t get enough exercise. But just how much exercise is enough. How can you tell if your dog is getting enough exercise. Different dogs will have different exercise needs depending on their breed, their size, their age, their overall health and other factors? No one would think of exercising a Pug the same way they exercise a Golden Retriever? The two dogs are different in virtually every respect.
