Exercise: Proper exercise, when based on your pet's age, breed and medical history, can have a dramatic impact on health and behavior. Managed activity lowers your pet's risk for joint disease, arthritis, obesity, diabetes, separation anxiety, and destructive behavior. Depending on your pet's age and breed this may be as simple as more play time with your cat, a walk around the block with your senior dog, or two to three hours of Frisbee with your new puppy.
