A perianal fistula is a painful opening in the skin around the anus of a dog. The condition affects German Shepherds most commonly, although other breeds can develop the problem. There are several possible contributing factors, including genetics, allergic skin disease, and alterations in immune system functioning. If your dog strains to defecate, has pain and bleeding around his rear end, seems constipated, licks his bottom excessively, or has a smelly discharge from the area, a perianal fistula is possible.

Losing Noah: Coming to Terms with Canine Cancer
Have you seen the TV commercial where a child comes running to his mother, so excited because their dog has learned a new trick? The mother is horrified, as she realizes the trick is the dog scooting across their carpet on its behind. Most people would probably find that very funny. I can't watch it. You see, a little scoot across the floor was the very first sign that our dog, Noah, had cancer. At first, we were so nonchalant about this incident.
Perianal Adenoma in Dogs
The tumour is invasive with a high mortality rate. The cancerous cells may invade regional lymph nodes and travel to the spine, lungs, liver and spleen via the bloodstream. The tumour may go unnoticed in the early stages and an abnormal mass or swelling in the region of the anus perineal area may only be recognised when the growth is large. Other signs of anal sac adenocarcinoma include problems with defecation, local pain or irritation, excessive drinking and urination, hind limb weakness and lethargy. The tumour cells produce a protein, parathyroid hormone related protein, which causes increased calcium levels in the blood, and may lead to hypercalcaemia.
