When starting to exercise a dog who isn’t in a regular exercise program, it is best to walk them frequently but for short periods of time, which reduces the rest time between walks, during which their joints will stiffen. A good start is 10 minutes of walking, three times a day. If your pet doesn’t experience increased stiffness, it can be increased on a weekly basis. Controlled, regular physical exercise is one of the core treatments for canine osteoarthritis, along with weight control, physical rehabilitation, and pain management. Exercise increases circulation to the muscles and joints, decreases stiffness in the joint capsule and soft tissues, reduces pain, maintains strength, and benefits the cardiovascular system. There are many simple exercises you can do with your dog to increase muscle strength and mobility. Obstacle courses: Make a course with broomsticks or small poles, spaced body-length apart, that your dog can walk over slowly. Three-legged stands: Ask your dog to stand and pick up one of their feet, causing them to shift their body weight to the remaining three feet on the ground.
