I have a small rescued hound (Gus) who recently sprained his right front paw. The vet prescribed reduced activity (crate) for a week. After 3 weeks of favoring/reducing the weight he places on his right paw and thus increasing the weight he places on his left leg, Gus has developed a clicking in his joint(wrist) above his left paw. The "click" happens when Gus takes pressure (lifts) his left leg while walking. Is this something I should be concerned with?
