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.
The obnoxious substance coming out of the anal glands is supposed to help dogs mark their territory when they defecate. In reality, anal glands can cause all kinds of problems in dogs and occasionally in cats. They can get blocked, infected or even turn into cancer.
Anal sac disease is caused by clogging or infection of glands called anal sacs located on each side of the anus. It is the most common disease of the anal region in dogs. The anal sacs are related to the scent glands in skunks and produce a small amount of foul-smelling liquid.
A 9-year-old emasculated male Spitz with tenesmus and constipation had a subcutaneous mass at the left ventral aspect of the anus with history of polyuria and polydipsia. A complete blood cell count, serum biochemistry panel, and urinalysis cystocentesis sample were evaluated. Abnormalities in the serum biochemistry panel included a mildly elevated serum cholesterol concentration 7. Furthermore, testing revealed an increased intact parathyroid hormone concentration
Perianal tumors are tumors that develop on or close to the anus. Dogs have several types of glands around the anus. Some of the material they produce is stored in the anal sacs, which are two small pouches located beside and slightly below the anus.

Anal sac squamous cell carcinoma SCC is a rare tumor in dogs. Only eight cases have been described in the literature, and previous reports of treatment only describe surgery or palliative treatment with non-steroidal anti-inflammatory drugs. We report a case of a year-old female neutered Labrador with locally advanced anal sac SCC.
The anal glands are small sacs found on either side of the anal opening of your dog. The lining of the sacs produces a small amount of liquid, which is eliminated each time your dog defecates. The development of a tumor in this area can be significant; even with the presence of a small growth there is the definite possibility that the tissues will be invaded and the cancer will spread metastasize. In some cases, the tumor can cause hypercalcemia elevated blood calciumleading to kidney failure.
Dogs and cats can function normally without these scent glands. Cancer can develop in the anal sac glands in dogs, but rarely in cats. In most cases, this tumor affects only one anal sac, but occasionally both left and right sacs are affected.
The perianal glands are sebaceous-like structures in the perianal skin of dogs, located close to the anus. Perianal gland tumors originate from these glands, and most commonly develop in intact, older dogs and spayed females. While benign tumors are generally harmless and can be easily treated, the malignant variety can create life-threatening conditions for your dog, and will need to be treated aggressively. Perianal gland tumors develop close to, or directly on, the anus in dogs, and originate from the perianal glands.
