Dogs And Movement

The primary advice most experts on human backs / spines recommend that walking is the very best exercise to keep your back in shape and to help heal injuries. 

Many dogs are susceptible to back injuries, either because of their anatomical structure, or because of age. While I am not a back expert nor veterinarian, I do believe that walks are good for your dog's back (and overall health). 

Many dogs are not walked. I don't think that is a good thing. If your dog needs training, then get it.

Plan accordingly.
