Anal gland trouble is one of the most common reasons dogs end up at the vet for something non-emergency, and yet most owners have never heard of these glands until their dog starts having issues with them. Here's a broader look at what can go wrong, from the mild and manageable to the kind that needs medical attention.
Impaction
The most common problem. The glands fill with fluid but don't empty naturally, so the fluid thickens and gets harder to release over time. Signs include scooting, licking, and that telltale fishy smell. Left alone, impaction tends to get worse rather than better on its own.
Infection
When an impacted gland isn't relieved, bacteria can take hold, leading to infection. This usually shows up as swelling, redness, heat around the area, and real pain when your dog sits or is touched near the tail. Infections need veterinary treatment, typically antibiotics, and shouldn't be managed at home.
Abscess
An untreated infection can progress to an abscess — a painful, swollen pocket that may rupture on its own. This is the most serious stage and needs prompt vet care, sometimes including drainage and a course of antibiotics.
What Increases the Risk
Smaller breeds, dogs carrying extra weight, dogs with chronic soft stool, and dogs with underlying allergies all tend to see more frequent gland issues. Diet plays a bigger role here than most people realize — firmer, well-formed stool does most of the natural work of emptying these glands during a normal bathroom break.
The Takeaway
Most anal gland problems start small and stay manageable if you catch them early — it's the ignoring-it-for-months version that turns into a vet visit. Knowing the signs, and having a proactive plan, makes all the difference.
