Our four-legged friends stand on their toes, ankles in the air, knees forward. Imagine doing that all day and you’ll have a better idea of the weight and stress your dog puts on his muscles and joints. It takes lots of energy, strength, and flexibility to chase squirrels, scratch behind ears, wrestle with playmates, jump on beds, and leap for toys.
Every now and then dogs overdo it, asking just too much of their front legs (shoulders, elbows, wrists, and toes) or back legs (hips, knees, ankles, and toes). Sprains and strains are common injuries.
