Signs of severe infection might include distinct bulges just beneath the surface on either side below the anal opening, drainage from the rectum or even one or more abscesses in the immediate area. Marc Abraham is a vet based in Brighton. This is the reason dogs smell other dogs' bottoms when they meet and greet, standing tense with tails erect to swap their own unique smells rather like individual fingerprints. Impaction results from blockage of the duct leading from the gland to the opening, with the gland usually becoming non-painful but swollen. Applying pressure to an anal sac impaction or infection could cause the gland to rupture, and lead to bleeding and painful complications for your dog.
Other signs include licking or biting around their anal area, chasing their tail, sitting uncomfortably, or even licking paws - both front and back - in sheer frustration.

Go Health Dog health information. They're not the stuff of dinner party conversations, but knowing how to spot a problem could save your dog a lot of misery. Domestic animals like dogs and cats have largely lost their ability to empty these glands voluntarily - unlike the skunk's world-famous pungent defence mechanism. The Kennel Club is not a veterinary organisation and is unable to provide general or case specific veterinary advice. Your dog's anal glands may spontaneously empty just by walking around, especially under times of stress, creating a very sudden unpleasant change in his odour. Some dogs seem unable to empty their glands fully on their own, causing the glands to become impacted and uncomfortable, and the dogs to drag or 'scoot' their rear-ends along the ground or more commonly your brand new cream-coloured carpet in an attempt to empty them.
