My dog is shaking and wining. He seems to be in pain from his feet which have been giving him a lot of trouble for the last few weeks. He doesn't want to walk anywhere. He has been to the vet twice now but they just sold me some wash. His feet seem crusty with dark patches between his pads. I have cut away as much hair as possible (He is maltese 14yo) and used the wash. Didn't help. Then I tried salt water and blow drying. He is eating fine and the vet says seems relatively healthy but Id like to give him something for the pain if that's what needs to make his life a bit better. Is there anything I can give him from home as I know they can take human antibiotics
