Buyer’s Guide: Choosing the Best High-Fiber Dog Foods for Constipation

Why High Fiber Food?

You might be wondering why, exactly, a high fiber food is a good choice when your dog has constipation. It’s because fiber—insoluble and soluble—can help regulate bowel activity. Insoluble fiber is the one that moves through the digestive tract and adds bulk to the stool, which helps to clear up constipation (or loose stools), but both kinds are good to have in a food. Fiber can also:

All of these things are excellent reasons for putting your dog on a food that’s higher in fiber!

What to Look for in a High-Fiber Dog Food

If you’re unsure what you should be looking for when it comes to high-fiber dog foods, take a look below!

Fiber

The first thing you want to look at in a dog food is how much fiber it has (obviously). You’ll find this listed under “crude fiber”. Fiber amounts in dog food come in a wide range. Many dog foods will only have 1–2%, while others will have 10% or more. Most dogs really only need 2–4% of fiber in their diets, but if your dog is suffering from constipation, they might need a bit more. We advise speaking with your vet to find out just how much your dog should be getting.

If you need to speak with a vet but can't get to one, head over to PangoVet. It's our online service where you can talk to a vet online and get the advice you need for your pet — all at an affordable price!

Other Ingredients

You’ll also want to look to see what ingredients are in a dog food other than the ones that provide fiber. Your pup will need plenty of protein, so check and see how much a food has and whether it’s high-quality. Real meat as the first ingredient is always excellent, though meat by-products and meat by-product meals among the first ingredients are fine as well.

Besides the protein source, you’ll want to check that the rest of the ingredients are wholesome and offer benefits for your pet.

Peas & Legumes

Ingredients to be wary of in dog foods are peas and legumes. Though much more research is needed into this issue, there have been some links between them and heart disease in dogs. You’ll need to figure out how you feel about these ingredients when buying a dog food for your dog (especially since many higher fiber dog foods contain these ingredients).

Price

Dog food can get extremely pricey if you aren’t careful. Shopping around for the best deals by looking for more than one food that contains the ingredients you like is helpful.

Reviews

Reviews from other dog owners are a great way to get a good idea of just how good a dog food is and how well it works for constipation. These reviews are often more honest than branding and marketing claims.
