Canine Anal Glands

If your dog is still smelly after his bath, his canine anal glands may be the culprit.

What are Canine Anal Glands?

Perhaps you've been there before? You notice your dog is beginning to smell a little rough, so you give him a good shampoo and think the problem is resolved, only to notice that there is a distinct odor about him as soon as he is dry. You might attribute that smell to rolling around in the yard, but where does it come from if he hasn't been out to do the deed yet?

Canine anal glands just may be the culprit in this kind of situation. The glands that are found just below the surface on either side of your dog's anus are actually sacs that produce an oily substance that emits a particularly foul scent.

What Are They For?

Dog anal glands provide your dog with his own individual scent, one that identifies him to and from any other dog. This is why dogs tend to sniff around each other's rears when they meet.

Under normal circumstances, the glands are activated when feces is passed out through the rectum, causing a small amount of the oil to be excreted in the process. Along with scent, the oil also helps lubricate the anal opening, making it easier for your pet to pass his stool.

Your dog can also express a bit of his personal eau de cologne when he feels provoked or excited. Ever notice how your dog will stand tensed with his tail erect in these circumstances? He's using his scent glands to advertise his territory.

Under most circumstances, anal sac secretions are extremely minute, so you usually won't see them or smell them yourself, although you may notice your dog's bedding becomes a bit smelly between launderings. It's when you can actually smell the odor emanating from your dog's rear quarter that there may be a problem going on.

About Anal Gland Infections

Your dog may happily pass through life without ever having any problem with his anal glands, but not all dogs are so lucky.

Occasionally, these glands can become infected. This usually happens when the oil isn't properly expressed over a period of time, giving it the chance to build up bacteria. This frequently happens when a dog's stools are soft and mushy; they lack the firmness required to put proper pressure on the glands as the feces is evacuated.

When an infection occurs, you will likely notice several signs that your dog is feeling uncomfortable.

These might include:

• Scooting his bottom across the grass or floor
• Excessive licking and chewing at his behind

Signs of a severe infection might include:

• Distinct bulges just beneath the surface on either side of the anal opening
• Drainage from the rectum
• One or more abscesses in the immediate area.

If you notice any of these signs, it may be time to have your dog's anal glands expressed to get rid of the infected fluid so the glands can function properly once again. However, this is best left to your veterinarian, because applying pressure to an extreme anal sac infection could cause the structure to rupture, leading to bleeding and painful complications for your pet.

Maintaining Your Dog's Anal Gland Health

Some dog owners prefer to use a little routine maintenance to head off anal gland problems by manually expressing the gland themselves before a grooming session.

This can be accomplished by covering the dog's rectum with a cloth and applying gentle pressure to the pea-sized lumps on either side. This will usually cause a small amount of oily liquid to emerge, but sometimes the secretion will squirt out if the glands are particularly full, hence the covering of the rectum with a cloth before you begin.

If this activity doesn't sound like something you'd feel comfortable with, you should know that many dog groomers will perform the task at your request. You should also be aware that not all dog experts agree that the anal glands should be interfered with in any way unless a dog is showing signs of a problem.

Conclusion

If you didn't know anything about canine anal glands before you read this article, you probably know more now than you ever thought you could. Whether or not you decide routine gland maintenance is a good idea for your pet, at least you'll know how to identify problems quickly and hopefully save your dog from the discomfort of a prolonged anal sac infection.
