Similar to humans, dogs need an adequate amount of fiber in their diet to maintain proper health. It aids in their digestion and acts as a prebiotic food source for your dog’s beneficial intestinal bacteria. Beneficial bacteria or probiotics help to prevent pathogenic bacteria overgrowth, promoting health in your dog’s colon. Increased fiber intake can even reduce the risk of cancer in dogs by speeding up the elimination of any carcinogens your dog has consumed. It’s essential for helping to maintain your dog’s healthy weight and with such a myriad of benefits for your four-legged friend, it’s understandable that you’re looking for ways to up their intake.

On this list, you’ll find 11 good fiber sources for your dog. We’ve split them up into whole foods you can use as treats, fiber supplements for when your dog is deficient, and high-fiber dog foods for regular feeding.

The 5 Best Fiber Sources for Dogs: 

1. Broccoli

Every parent tells their kid to eat their broccoli if they want to grow big and strong. But it’s not just kids that can benefit from broccoli. This plant is nutritious for your dog as well. It packs in more nutrients than almost any other plant from the cabbage family and is loaded with fiber that’s great for your dog. Broccoli is completely safe for canines to eat, but that doesn’t mean your dog is going to be fond of it!

2. Carrots

Most people know that carrots can help your eyesight, but they pose a lot more benefits than just that, for your dog as well as you. These crispy orange snacks are loaded with carotene among lots of vitamins including A vitamins, B6, and vitamin K. This will help keep your dog’s eyes in good health while providing a great dose of fiber.

3. Apples

Apples are a sweet, natural treat that many dogs love. Not only are apples packed with fiber but they’re also loaded with vitamins A and C. Plus, apples are very low in fat, so they won’t contribute to weight gain. But you must take care to remove the seeds and core first. Not only do these pose a choking hazard, but the seeds also contain cyanide, which can be toxic for your dog.

4. Pumpkin

We often think of pumpkins as a festive orange decoration to carve up at Christmas time. But this squash is also a tasty treat that can provide loads of nutrients and fiber for your dog while being very easy on their stomach. You can easily blend up some pumpkin and freeze it to give your furry friend a sweet, cool treat on a hot summer day.

5. Brown Rice

Although grain-free diets have been becoming more popular, grains are still a great way to provide your dog with adequate amounts of fiber. You’ll find brown rice in many high-fiber dog foods because it’s rich in fiber and healthy for dogs. Each cup of cooked brown rice yields 3.5 grams of fiber, helping to boost your dog’s overall fiber intake with a single cup.
