Rockstar appears to have gotten into a fight. . .
The vet thinks that it was against three dogs.
Since he only has three big wounds, I think he held his own pretty well.
The tub connecting two of the wounds on back/shoulders is there to drain fluids and prevent infection. MaBell is cleaning and medicating him daily (with a muzzle, of course).
These pictures were taken about a week after the fight, so it is looking much better now!
