After the "hyrdo therapy" takes just over 30 minutes to hose down all 3 legs, and presntly we do that twice a day...may up it?

The vet told me the scum around the wound was no big worry (just remnant medication etc.) but on a warm day I think I will get the rest of it off with some WARM water and a rag. I just don't like the look of it. However, it's rained many of the times I've been hosing so anything extra I just avoid.
