5 Best High Fiber Dog Foods for Anal Gland Problems

Anal glands are scent glands located around the rear of a dog. They are naturally expressed whenever a dog defecates that acts as another way your dog marks their territory. But sometimes your dog can have issues naturally expressing their anal glands.

This can be due to a health issue or a diet issue. When your dog does not have enough fiber in their diet they do not use the bathroom regularly and risk their anal glands building up.

Try switching them to one of the best high fiber dog food for anal gland problems if you think that your dog may be having an issue with their anal glands. These types of foods add more fiber to your dog’s diet to create firmer feces that naturally presses against their anal glands to express them.

This way, your dog can avoid any serious medical issues caused by anal gland fluid buildup. Not every dog food has enough fiber to help your dog though. To help, we’ve put together a list of five dog food brands with higher protein content.

Bottom Line

You might not even realize that your dog is having anal gland issues until they become so swollen your dog is uncomfortable. If you notice your dog scooting across the floor frequently, licking their rear constantly, sitting uncomfortably, or having swelling in the area they might be suffering from anal gland buildup.

You can help your dog by expressing the anal glands yourself to relieve the tension of the buildup, but that will only work in that instant. It cannot prevent buildup in the future.

What can help prevent buildup in the future is adding more fiber to your dog’s food. You do not want to overdo it either as that can cause stomach issues and diarrhea in your dog.

You do not have to add the extra fiber yourself but instead can simply switch to dry or wet dog food that has the extra fiber content.

The foods that we have suggested are some of the better high fiber diets that can also work for weight control.

But if you do not have access to any of them check over the ingredient list of the dog foods you have access to and if the fiber content is higher than 5% that’s good food to start on.
