If you’re looking to boost your dog’s fiber intake without switching their food entirely, here are some simple and natural ways to do it:

Pumpkin (plain, canned, or cooked)

A popular favorite! It’s gentle on the stomach and great for digestion. A spoonful or two of plain, cooked pumpkin (not pumpkin pie mix!) mixed into their regular food can work wonders.

Green Beans

Low in calories and high in fiber, green beans make an excellent snack or meal topper — crunchy and satisfying! Just make sure they’re plain, no added seasonings or oils. Chop them into small, manageable pieces.

Sweet Potatoes

Cooked and mashed (no seasoning), these are packed with fiber and vitamins. Just don’t go overboard on portions.

Carrots

Raw or steamed, carrots are a fiber-rich treat that also support dental health.

Apples (No Seeds or Core)

A crunchy, sweet option in moderation. High in fiber and a great source of vitamin C. Think of them as a healthy treat, not the main fiber source.

Ground Flaxseed or Chia Seeds

Just a small sprinkle over their food can boost both fiber and omega-3s.

Oats

Cooked plain oats (no sugar or flavoring) are a gentle source of soluble fiber and can be mixed into meals.

Can I Give My Dog Fiber Every Day?

Yes, you can give your dog fiber daily — but like all things in your dog’s diet, it’s about balance and the right kind of fiber. Here’s what to keep in mind:

Daily Fiber Is Safe in the Right Amount

Most dogs benefit from a consistent amount of fiber in their meals, but too much can cause gas, bloating, or diarrhea.

Start Slow and Steady

If your pup isn’t used to a high-fiber diet, introduce it gradually to avoid tummy troubles.

The Right Amount Depends on Your Dog

Factors like your dog’s breed, age, size, and activity level will influence how much fiber they need.

Natural Sources Are Great

Daily fiber doesn’t always mean supplements—foods like pumpkin, green beans, and oats can do the trick.

Daily Fiber Needs Hydration

Fiber absorbs water, so consistent access to fresh, clean water is essential to prevent constipation.

Variety is the Spice of Life (and Fiber)

Instead of relying on one fiber source, mix it up! A little pumpkin one day, some veggies another, helps provide a balanced intake.

Watch for Signs

Healthy poop, less scooting, and improved digestion are good signs fiber is working. If you notice constipation or discomfort, check in with your vet.

Vet Guidance Matters

Especially if your dog has ongoing digestive issues or you’re trying high fiber dog food for anal gland problems, your vet can help guide the right daily amount.

FAQ

What is the #1 high-fiber food?

The #1 high-fiber dog food really depends on your pup’s size, needs, and health goals—but formulas like Hill’s Science Diet Light and Royal Canin Weight Care are often top picks recommended by vets for weight and digestion support.

What is the best fiber to give a dog?

The “best” fiber varies! Soluble fiber (like in pumpkin) aids digestion, while insoluble fiber (like in some veggies) adds bulk. A mix from whole foods is ideal. Always introduce fiber gradually and watch for your dog’s response.

Is IAMS dog food high in fiber?

Yes, IAMS high-fiber dog food offers formulas with added fiber to support healthy digestion and weight management. Many recipes include natural fiber sources like beet pulp, making it a solid option for pet parents looking to boost their dog’s fiber intake.

What fiber is good for dogs with constipation?

For dogs struggling with constipation, soluble fiber is often beneficial as it draws water into the colon, softening stool. Good options include plain canned pumpkin (a popular choice!), psyllium husk, and cooked sweet potatoes. Make sure to introduce fiber gradually and that your dog drinks plenty of water.

What are two foods very high in fiber?

Two foods very high in fiber for dogs are pumpkin and sweet potatoes. These natural ingredients are rich in soluble fiber, which aids digestion and helps maintain healthy bowel movements, making them great additions to a fiber-rich diet.

Is rice high in fiber?

While brown rice offers more fiber than white rice, neither is considered high in fiber compared to other sources. Brown rice typically contains around 3-4 grams of fiber per cooked cup, while white rice has less than 1 gram.

Is rice good for dogs?

Absolutely! Rice can be a real comfort food for dogs, especially when their tummies are a bit off. It’s easy on their system and gives them a little energy boost.

What is the best dog probiotic?

It’s tricky to name the best, as it depends on your dog’s specific needs! Look for probiotics with multiple, well-researched strains (like Lactobacillus and Bifidobacterium) and a guaranteed CFU count. Consulting your vet is the best way to find the perfect probiotic to support your pup’s gut health.
