Barker the Elder came in the house one morning with blood splattering - deep cut on the pad. Called the vet. Pack it with generic or band name preparation H (stops the capilary bleeding), add some triple antibiotic and that's it. Clean it if it gets dirty outside (or inside). You could call your vet and ask what they think of this approach. They should be fine with it and be willing to talk to you over the phone.
