My view: it never hurts to call the vet. The techs that answer the phone at my vet are very knowledgeable and don't ALWAYS say bring the pet in. Hence I trust them when they DO say that. You could call and explain and ask if it is OK to put xxx on it. Don't leave it open ended, as in "what should I do?"

Fenway, please let everything heal up!

Hey, is this the leg that was way up in the air in the sleeping photo?

I liked the idea posted earlier of putting something on and letting the air get to it to let it keep healing. I'm never sure (even for myself) when a sore is best covered and when it is best open to the air.

Good luck.
