Question
My dog recently ran away and when he came back he had a cut that looked
like a small hole on his left rear side near his thighs. We thought it was
a small scab because it was not bleeding, so we let it be. Two days later,
my dog keeps on licking in it and then it started to bleed and we took him
to the emergency vet. They just gave him a shot to fight away infection
but couldn't do much since it was on the weekend and our vet was closed.
The hole on the side has continue to bleed a little at a time, and we have
place cotton bandages on it....but I am not sure if that is the best thing
we could do. My dog has a cone on his head to prevent him from licking the
wound. What can we put on the injury to make it from turning swollen or
red? Should we take the bandages off or leave it on? Please help.
What do think this could be and how can I treat it?


Answer
I would recommend going back to the vet.  Your dog should be placed on oral antibiotics for 10 days.  You can clean and flush the area with an epsoms salt solution or saline.  And I would let it open to drain but keep the collar on to avoid him from licking it.
