After our vet visit yesterday, Pistol seems not to be doing as well as he was before the visit. He just is far less likely today to use the leg when we go out - just mostly hops on 3 legs. He was using the leg at least 50% of the time before. I am assuming it is due to draining that serum off. I mean, I would think getting it off would make it feel better, but having that needle poked around in there would probably make it sore? So hoping he will be back on track by tomorrow. The incision does look better today and isn't seeping at all.
