Cooper has been limping a little bit for a few days. The limp seemed to get better then worse.
I couldn't find a problem with his paw or the pads of his feet. I felt all the way up his arm and felt what may have been a little swelling but it didn't seem to bother him when I touched it.
So I massaged it for about 10 minutes or so. He allowed it and seemed to really appreciate it.
And the limp has gotten better since then.
