Last Sunday I noticed that my boy was licking his rear end non stop for like a hour so I took him to the vet as he was due for his second Flu shot anyway. Well it turns out that his anal glands needed to be expressed and that he basically licked himself raw. We also wanted to get the 4DX tests done because we have seen multiple ticks on him. Well I got a call Sunday night from the vet and she said that he showed a low positive for Anaplasmosis. She wanted to send in the blood to confirm and to find out how positive he was so that she can figure out what treatment if any was necessary. The problem we are still having is that he is still licking himself alot and the area is now pink and there was a little blood on his anus. what should we do to clean it and stop him from licking it? he was put on Metronidazole for 1 week.
