Pet's info: Dog | Labrador Retriever | Male | unneutered
Hello. I have a male labrador (20 months old). He is frequently licking his anus and biting at base of his tail. He is fidgety, not sitting at a place and keeping his tail between his leg and trying to bite it. He was recently treated with an anti parasite medicine. He is not letting anyone touch his tail.

You will need to do regular flea prevention as these signs are typical for irritation by flea bites. Roko may also have impacted anal sacs. If, after doing flea prevention the biting and licking does not stop or if you see injured skin,. a bulge near the anus , you need to take Roko to your veterinarian for an exam. Impacted anal sacs need to be evacuated as they are very painful and can also get infected.
