Hello Everyone: I am new here, and in need of assistance. My dog has been licking his anus, occasionally for a couple days now. Today, it is excessive. I took him out to go potty, and after going he ran around in circles licking his anus and did not stop. I tried to see what was going on back there, but this made his extremely upset. He had his anal glands expressed at the vet a couple of weeks ago. His stools have been "normal", no diarrhea or constipation. He was also dewormed at this time, and his poop sample came back normal. Any thoughts? Thank you in advance.
