We noticed Oliver was limping two days ago. Not a constant limp but it looked like his leg would give out a bit every couple of steps. He ran around fine when we were playing on the beach but as soon as he got to some mulch he was really ginger and started to limp again. We were so worried he might have tore something but looking at his paws he has a small spot that looks cracked. When we touch it he pulls back and winces with pain. Its such a small thing though, its hard for me to imagine that its causing him this much pain because he never complains about anything but I've never dealt with it before so dont have a point of reference. Has anyone had experience with this? what type of treatment did you do? thanks.
