Anal sac disease, also known as perianal disease, is a widespread problem in dogs. The anal sacs are two glands that fill up with a gooey substance called porphyrin

The function of these glands is to provide lubrication for fecal matter while it is being expelled from the body. In dogs, anal sac disease can occur when the glands become infected or inflamed. 

Unfortunately, pus and other fluids can gather in the sacs when this happens. Therefore, it leads to a lot of discomfort for the dog.

How anal sacs works?

The anal sacs location is on either side of the rectum, just inside the animal’s anus. Generally, these sacs contain a thick, brown fluid. Also, it releases oily fluid whenever the dog defecates. 

The fluid helps to lubricate feces. So they can pass through the rectum and out of the body. Dogs use this lubrication to help avoid developing hairballs in their digestive tract.

Does anal sac in dogs cause a problem

Anal sac disease in dogs is a controversial topic. It does not have a clear answer as to whether or not it is truly a health issue. 

Some veterinarians would say that the sacs are just part of the dog’s anatomy and do not represent any medical concern. But they can be impacted by other issues within the dog’s body. 

For example, suppose your dog has an underlying gastrointestinal disorder (such as gastritis). In that case, the anus may become inflamed and develop small bumps on its surface. 

Also, these bumps will have little bits of food trapped inside them. If left untreated, this condition can lead to severe infections of the dog anal glands and cause anal pain for the pet. 

Typically, this is why most vets recommend that owners keep their pets from eating certain foods until anal sac problems resolve.

How will I know if my dog has anal sac problems?

Anal sac diseases can occur in dogs, and it is essential to know the signs of the condition. The anal sacs are two small glands about 3 inches (8 centimeters) long on either side of the anus. 

They produce an odiferous liquid that masks other scents near the dog’s rear end. In addition, an infection in this area can have to swell around the anus. 

Therefore, it can cause difficulty walking or sitting down. Perhaps, you don’t find any dog grooming near you. As a result, it can develop an anal sac disease in dogs without regular grooming. 

Usually, the anal sacs are located near the rectum and release fluid when the dog is excited or frightened. MORE: What is a Droopy Dog, and why is it called so?

Preventing Anal Sac Disease in Dog

Most people think that dog anal sacs only produce a scent when full of feces. However, this is not true, as dogs can also have a buildup of secretions from glands around the anus which will cause an infection if not cleaned out.

What is the best dog food for anal gland problems?

Some dogs exhibit anal gland problems, leading to scooting and excessive licking. The best dog food for anal gland problems is a dry kibble with a medium-low fat content.

Both wet and dry foods contain essential nutrients for dogs. Still, wet food contains water and carbohydrates. 

It helps with hydration and staves off the urge to eat the dog’s feces. Dry food does not have these benefits and may cause overeating.

Suppose your dog has an underlying problem (such as fleas or another skin disease). In that case, it might be beneficial to give him some additional nutrition to supplement his diet.


Dog anal glands disease is prevalent but often overlooked by pet owners. The anal sacs are located at the opening of the anus and produce an oily fluid with a foul odor. 

If these sacs become impacted, they can swell and cause your dog to scoot across the floor or exhibit other behaviors that signify discomfort. 

This condition will usually resolve itself with time and proper treatment if caught early enough. However, it can be pretty painful for dogs, and adequate treatment should prevent complications such as infection.
