Anal Gland Abscess
Dogs and cats have 2 scent glands located at the 4 and 8 o'clock positions around the anus. They are normally pea sized and produce a foul fishy smelling liquid which is squirted onto the faeces as a way of marking a pet's territory.
Pet skunks have the worst smelling anal glands.
Some breeds of dogs (e.g. Cavaliers) can have continual problems with blocked anal glands. Affected pets drag their bottom along the ground (scooting) and/or chew their tail base (looking like they have a flea problem). The other cause of scooting is a tapeworm infection, when small rice grain sized worm segments crawl out of the anus and move like leeches around the sensitive skin.
Anal gland can be surgically removed if they cause continual problems.
Sophie, a 6 year female cat presented with a firm painful swelling over her right perineal region. There was heat, swelling and redness present, and she was reluctant to go to the toilet as it hurt every time she tried tp pass a motion.
We placed Sophie on an IV drip and gave her Alfaxan IV to induce anaesthesia. She was then placed onto Isoflurane as a gas anaesthetic.
The area was clipped and sterilised. An incision was made into the abscess and pus was released. We removed a dried up piece of pus that had a cheesy consistency. The area was flushed with saline and a rubber Penrose drain was placed in the wound.
Sophie was sent home with antibiotics (Amoxyclav) and pain relief (Metacam drops for cats)
The drain was removed 4 days later and the skin stitches were taken out at 10 days.
Sophie made a full recovery.
