Finding the right balance of exercise and activity for a Chihuahua is important. This breed is a contradiction; he is the smallest of all the toy sized dog breeds yet has an abundance of energy that some say is at the level of some medium and large sized dogs.
While the Chihuahua does well in just about any living environment, even small apartments since he does not take up much room, he does need to have daily exercise. Due to his tendency to become hyper, this dog needs to have daily outdoor activity in order to release pent-up energy.
If not, a Chihuahua may be prone to destructive behavior such as chewing. Therefore, a well-exercised Chihuahua is a happy and more well-behaved dog. With that said, due to his size there are exercise restrictions that an owner should follow.
