How to Add Fibre to a Dog’s Diet?

High-fibre food should be included in your dog’s diet, but sometimes it’s not easy to choose the right foods. As a responsible pet parent, you must know what foods to include and how much to feed.

Fibre mainly comes from plants and doesn’t necessarily get digested. Instead, it helps in other important functions, such as it helps digestion by serving as food for the good bacteria that live there[1].

That’s why soluble fibres are called “prebiotics,” because they stimulate the growth of these good bacteria. It may sound strange that fibre can both speed up bowel movements and at the same time, stop diarrhoea in dogs.

Now that we have understood the advantages of adding fibre to a dog’s diet. Let’s explore some useful tips on selecting the right foods for their meal:

  • Pumpkin: Pumpkin is a great source of soluble fibre. Feed plain without added sugars or spices.
  • Beet Pulp: This is often found in commercial dog foods. It contains both soluble and insoluble fibre.
  • Flaxseed: They are a great source of omega-3 fatty acids and fibre and also benefit dogs’ skin, coat and digestive health. Flaxseeds also ensure better nutrient absorption in the stomach.
  • Lettuce: Lettuce such as romaine or green leaf is low in calories and contains high fibre. A healthy treat option for dogs.

  • Carrots: Besides being a good source of fibre carrots also promote the dental health of your dog.
  • Apples: Before feeding apples to your dog always remove seeds and anything difficult to chew in the core, apples are a fibre-rich snack.
  • Green Beans: High in fibre and low in calories. Green beans are a healthy and crunch treat for your dogs.
  • Sweet Potatoes: They are rich in fibre and minerals. Cooked and mashed sweet potatoes are delicious options.
  • Oatmeal: Cook plain oatmeal without any flavour or sweetness, this will fulfil your dog’s occasional hunger.
  • Brown Rice: Compared to white rice, brown rice has more fibre and nutrients.
When choosing high-fiber foods, it's important to select foods suited for your dog's breed and size. For example, some of the best dog food for huskies contains fish, meat, and fiber sources like brown rice.

Do Dogs Need Fibre?

Fibre is good for dogs as it helps them to digest food. Fibre comes from plants, fruits, grains, vegetables, and beans. It also makes dog poop softer and bigger.

Fibre also promotes gut health and stomach work better. Fibre helps to break down food and get all the nutrients needed for dogs. It can also keep blood sugar levels steady, which is important as dogs are always ready to eat. Most vets recommend a high-fibre, low-fat diet.

“Fiber slows the entrance of glucose into the bloodstream and helps your dog feel full. Low-fat foods have fewer calories. Together, the diet can help your dog eat less and lose weight”, says Dr Amy Flowers from WebMD.
