We’re all about feeding our dogs the healthiest foods possible. In addition to cancer-fighting foods for dogs and brands recommended by vets, probiotic dog food is an excellent way to influence your dog’s health on many levels. Dogs normally have a balance of good and bad bacteria and yeast in their intestines. Sometimes the “bad” bugs overpower the good ones, but antibiotics can kill beneficial bacteria, too. Intestinal parasites, illness or stress can also knock out the good bugs and lead to nasty side effects, from diarrhea and bad breath to allergies and obesity.
Probiotics (found in many natural dog foods) are friendly bacteria that help battle infections, strengthen the immune system, synthesize vitamins and nutrients and assist in the digestion process. They reduce gut inflammation that leads to digestive upset, gas and constipation. Plus, they can increase your pup’s energy levels and even improve bad breath.
Although incidents of pet food poisoning are rare, if your dog has recently experienced diarrhea, undergone antibiotic treatment or simply needs an energy and health boost, probiotics may offer a solution. Today, probiotic products are not only available in dog food but also in the form of probiotic bites and toppers. Read on for the best options on the market.

What to look for when buying probiotic dog food
Not all dogs need probiotics, but they still may benefit from them. While you should always check with your vet for dog food and health advice, probiotics are considered safe. You can also safely add probiotics to your dog’s regular food as healthy treats. Foods like unflavored plain yogurt, kefir or raw organ meats contain healthy probiotics. Another option is to offer your dog commercial probiotic supplements, pills or powders like Purina Fortiflora. But probiotic dog food is the easiest and most convenient way to help your dog feel better.
Look for these fancy Latin names of probiotics. Find them alone or in combination toward the end of the food ingredient list on a dog food label:
- Lactobacillus acidophilus
- Lactobacillus casei
- Bifidobacterium breve
- Enterococcus faecium
- Bifidobacterium lactis
To keep friendly bacteria healthy, foods must also contain plant fiber nutrients called prebiotics to feed and maintain the good bacteria. Look for fruits, vegetables or whole grains on the ingredient list. Most times, you won’t see “apple” or “dandelion greens” listed, though. Instead, look for these prebiotic terms:
- Galactooligosaccharides
- Fructooligosaccharides
- Oligofructose
- Chicory fiber
- Inulin
