Anal Gland Cancer in Dogs
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.
Anal Sac Tumors
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.
