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. The liquid is normally squeezed out during defecation. Small breeds are predisposed to anal sac disease; large or giant breeds are rarely affected. Anal sacs may become clogged impacted , infected, abscessed, or cancerous.
From time to time we all suffer the discomfort of stomach ache — and dogs are no different. If you suspect your dog has stomach ache, there are actions you should take to help him feel comfortable and reduce the risk of it developing into sickness or diarrhea. Not quite. If your dog is guzzling water, there's a good chance it goes deeper than thirst. Keep an eye on it and make sure to call the vet if symptoms appear or worsen. Pick another answer! That's right!
Impacted anal glands are often the first stage of anal sac disease. As the impacted anal glands become swollen and distended, they become inflamed and can make it painful for your dog to pass feces. This second stage of inflammation is referred to as sacculitis. Bacteria can begin to grow and cause an infection. The final stage is when an abscess forms.
The anal glands on both sides of the anus are usually drained naturally when your dog has a bowel movement, but sometimes the fluid becomes too thick to be expressed and it will become impacted clogged up. After the anal gland has been impacted for a while, it becomes infected and swollen. Finally, the infection will cause an abscess that is very painful for your dog. You will need to take your dog to the veterinarian so he can drain and clean the anal gland. The veterinarian will probably give your dog antibiotics in this case.
