Can Food Cause Anal Gland Issues in Dogs

Can Food Cause Anal Gland Issues in Dogs

Anal gland problems are an unpleasant but surprisingly common issue in dogs. These small glands, located on either side of a dog’s anus, produce a smelly secretion used for scent marking. When functioning normally, the glands empty during bowel movements. But if they don’t empty properly, they can become impacted, infected or even abscessed. One of the most common contributing factors to this issue is diet. What a dog eats plays a direct role in stool consistency, which in turn affects anal gland health.

How Diet Impacts Anal Gland Health

The firmness of a dog’s stool is key to healthy anal gland function. When stools are firm and bulky, they apply natural pressure to the anal glands during defecation, helping them empty as intended. If a dog’s diet is low in fibre, too soft, or inconsistent, their stools may not provide enough pressure to clear the glands. Over time, this can lead to a build-up, discomfort and the risk of infection. Dogs with frequent soft stools or diarrhoea are especially prone to anal gland issues, and this often ties back to what they’re being fed.

Common Foods That Can Contribute to Problems

Certain ingredients in commercial dog foods can lead to soft stools or digestive upset. Foods with high levels of fat, artificial additives, or poor-quality fillers like corn or soy may irritate the gut. Sudden changes in diet or feeding table scraps can also disrupt digestion. Dogs with food sensitivities or allergies may experience inflammation in the gut, leading to irregular bowel movements and—by extension—anal gland problems. Low-quality protein sources and lack of dietary fibre are two major red flags when it comes to gland health.

What to Feed to Help Prevent Anal Gland Issues

A high-quality diet that supports firm, regular stools is key. This often includes foods rich in natural fibre, such as pumpkin, sweet potato or brown rice. Some dogs benefit from a diet that includes limited ingredients, avoiding common allergens like beef, chicken or dairy. A raw or gently cooked diet may also help certain dogs, especially those with persistent digestive issues. Including probiotics or prebiotic-rich foods can improve gut health and overall stool quality, helping reduce the chances of anal gland build-up.

Can Food Allergies Trigger Anal Gland Problems

Yes, food allergies or intolerances can contribute to ongoing anal gland issues. When a dog eats something their body reacts to negatively, it can cause chronic inflammation in the gut, soft or runny stools, and irritation near the anus. Over time, this inflammation can lead to recurring gland impaction or infections. If a dog consistently has gland problems, it’s worth considering whether they might have an undiagnosed food sensitivity and working with a vet to try an elimination diet or allergy testing.

Other Signs of Food-Linked Anal Gland Issues

If your dog is scooting, licking their rear excessively, straining to defecate, or showing signs of discomfort after meals, food may be a factor. Chronic gas, bloating, inconsistent stools, or frequent changes in appetite could also be signs that their diet isn’t suiting them. These symptoms are worth noting and discussing with a vet, especially if they appear alongside anal gland flare-ups.

How Fibre Helps Anal Glands
Soluble and insoluble fibre both play roles in stool formation. Insoluble fibre adds bulk, which helps press on the anal glands during bowel movements. Soluble fibre slows digestion slightly, helping firm up soft stools. Together, they encourage proper gland expression. Natural sources include pumpkin, oats, carrots, and flaxseed.

The Role of Hydration
Hydration affects stool consistency, too. Even a good diet won’t produce healthy stools if a dog is dehydrated. Dogs eating dry kibble may be more prone to soft or inconsistent stools if they aren’t drinking enough water. Including moisture-rich food or broth can help balance this.

High-Fat Diets and Anal Gland Trouble
Diets that are too rich or fatty—especially human food or high-fat dog treats—can lead to softer stools and even mild pancreatitis, both of which can interfere with normal gland emptying. Dogs on rich diets may also be more likely to develop inflammation in the lower bowel, affecting gland function indirectly.

Small Dogs Are More at Risk
Smaller breeds like Chihuahuas, Dachshunds and Toy Poodles tend to experience more anal gland issues. Their smaller frame often means less muscle tone around the anal area and smaller stools that apply less pressure to the glands. This makes diet even more crucial in managing the problem.

How Often Should Glands Express Naturally?
In healthy dogs with proper diet and regular bowel movements, anal glands usually express themselves without intervention. If your dog needs frequent manual expression, it’s a sign something’s off—often diet-related. While occasional gland issues happen, frequent ones usually point to a larger digestive imbalance.

How to Tell if Diet Is the Issue
If your dog’s anal gland problems began after switching food or treats, that’s a clue. Keep track of stools—if they’re often loose, irregular or too small, you may need to adjust fibre, fat content or remove potential allergens. A food diary can help track patterns and spot triggers.

Can Supplements Help?
Yes. Fibre supplements like psyllium husk or canned pumpkin (plain, not pie filling) are often used to bulk up stools. Omega-3 supplements can help reduce inflammation in the gut and anal area. Probiotics support digestive health overall, improving stool consistency and regularity over time.

Summary

Yes, food can absolutely cause or contribute to anal gland issues in dogs. Diet directly affects stool consistency, which plays a crucial role in whether the anal glands empty naturally or become a problem. Poor-quality ingredients, low fibre, or food allergies can all lead to trouble. Feeding your dog a balanced, high-fibre diet with quality ingredients can make a big difference, helping support digestive health and reducing the chance of future discomfort. If anal gland problems are frequent, diet should be one of the first things to review.
