My little Rottie has seemed a bit out of sorts today, which I'd put down to her arthritis playing up. However I've checked her paws and there seems to be a sore on the big pad of her back left paw. It's like the top layer of skin has come off - looks red and sore. There doesn't seem to be any inflammation.
Should I take her to the vet, or can I treat it (salt water and antiseptic?) and keep and eye on it in the first instance? Should she still get a walk tomorrow or just a run round the garden? We can't over exercise her because of the arthritis anyway so I'm not too worried about not taking her for a day and she's really lazy .
