Constipation in dogs can be stressful for both pets and their owners. It often causes discomfort, loss of appetite and reduced energy. One of the most effective ways to help your dog stay regular is by feeding a high-fibre diet. Fibre supports healthy digestion, regulates bowel movement and promotes gut balance. This guide highlights the top 15 best high fibre dog foods recommended by vets and nutritionists to relieve constipation and maintain digestive health.

Why Fibre Is Important for Dogs

Fibre is an essential nutrient that keeps your dog’s digestive system working properly. It helps food move smoothly through the intestines, adds bulk to the stool and supports beneficial gut bacteria. There are two types of fibre — soluble and insoluble. Soluble fibre absorbs water and helps soften stool, while insoluble fibre adds structure and prevents blockages.

A balanced diet containing both types keeps digestion steady and helps prevent issues such as constipation, diarrhoea or bloating. Many high-quality dog foods today include natural fibre sources such as brown rice, beet pulp, pumpkin, oats and sweet potato.

Signs of Constipation in Dogs

Dogs usually pass stool once or twice daily, but if your pet hasn’t gone in more than two days or seems to strain, constipation might be the cause. Other signs include dry or hard stools, lack of appetite, lethargy and discomfort when sitting or walking. Chronic constipation can lead to more serious problems if not addressed, so identifying symptoms early is important.

How High-Fibre Food Helps Constipation

Feeding your dog high-fibre food increases stool bulk, absorbs moisture and encourages bowel movement. Fibre also slows digestion just enough to ensure proper nutrient absorption. The result is a comfortable, healthy gut and consistent energy levels. Dogs that regularly eat fibre-rich diets are also less likely to develop weight issues or digestive disorders.

Feeding Tips for Constipated Dogs

When transitioning to a high-fibre diet, make the change gradually over seven days to avoid stomach upset. Ensure your dog drinks plenty of water, as fibre absorbs moisture and works best when hydration is adequate. Keep feeding portions consistent and avoid giving too many treats between meals. For treats, choose natural dog snacks or small bites that are low in fat and sugar.

Feeding your dog from a clean, stable dog bowl and maintaining a comfortable sleeping area using a soft dog bed also contribute to overall digestive comfort.

Additional Ways to Support Digestive Health

Alongside a fibre-rich diet, regular exercise helps stimulate bowel movement. Taking your dog for short walks after meals can naturally encourage digestion. Avoid sudden diet changes, maintain a balanced feeding schedule and check for dehydration, which can make constipation worse. If your dog’s symptoms persist, consult your vet for professional advice.
