Probiotic Foods for Dogs

  • By Raquel Astacio

Cups of yogurt

Probiotics provide powerful health benefits for dogs by maintaining adequate levels of “good” bacteria in the intestines to counteract “bad” bacteria responsible for a host of infections and illnesses. Since the canine digestive tract is comparable to the functioning of a dog’s immune system, keeping intestines stocked with probiotic bacteria is essential to a dog’s lifelong health and well-being.

4 Foods That Contain Probiotics


Yogurt is chock-full of beneficial probiotics (described as “active or live cultures on yogurt containers) and can be fed safely to dogs to sustain levels of “good” bacteria in his gut. Similar to sour cream because it is a type of curdled milk but with reduced fat content, yogurt is made when lactose fermentation initiated by probiotic bacteria produces lactic acid. When lactic acid interacts chemically with milk protein, yogurt adopts it characteristic tang and texture.

“Good” bacteria found in yogurt are bifidobacteria, lactobacilli, S. thermophilius and many other bacteria that help prevent a variety of chronic gastrointestinal diseases and fungal infections from making dogs ill. Yogurt can also help counteract the effects of antibiotic therapy, especially diarrhea, vomiting and irritable bowel syndrome.

Depending on a dog’s weight, owners can add one or two tablespoons of yogurt to wet food once a day to maintain their pet’s gut health.

Soft Cheeses

Some probiotic bacteria can’t survive the strong acidic environment of a dog’s GI tract and never make it to his intestines. However, bacteria found in fermented soft cheeses can live in erosive gastric juices and find their way to the intestines intact. Swiss, Gouda and cheddar cheeses contain lactic acid bacteria that kill infectious bacteria, enhance absorption of nutrients from digested food and relieve constipation.


Buttermilk is an excellent source of probiotics because live cultures are added to help ferment sugars in buttermilk. Dog owners will need to give their pets buttermilk right from the carton, since heating or cooking buttermilk destroys the “good” bacteria. Like soft cheeses and yogurt, buttermilk also contains lactic acid bacteria beneficial to the health of a dog’s GI system.

Powdered buttermilk can be bought in select stores and sprinkled on wet food. In addition, buttermilk powder can help eliminate “tear staining” in dog breeds susceptible to runny eyes, such as English bulldogs, cocker spaniels, boxers and poodles.


Similar to yogurt but with a less dense texture, kefir is made using all types of milk–cow, goat, rice or coconut. It has a refreshingly tart flavor and contains loads of probiotic bacteria, yeast, vitamins and proteins.

Lactose Intolerance, Dairy Products and Dogs

Some dogs suffer from lactose intolerance after consuming dairy products. Symptoms of lactose intolerance are diarrhea, flatulence, nausea and stomach cramps. Lactose is a sugar found in milk that must be broken apart by an enzyme–lactase–before it can be digested properly. Dogs with enough lactase in their bodies may experience minimal to no signs of lactose intolerance while other exhibit more severe symptoms.

Milk, cheese and yogurt can affect dogs in different ways. For example, dogs lacking the lactase enzyme may become constipated if they eat cheese. Alternately, milk and yogurt are more likely to induce loose stools in lactose intolerant dogs.

For dog owners who want to give their dogs yogurt, they might try feeding them yogurt made from upasteurized, grass-fed milk or supplementing their meals with non-dairy yogurts made from soy or coconut milk.

Be Weary of Probiotic Enhanced Dog Food

Do not fall prey to the marketing of commercial dog food that claim to contain probiotics. Several studies have shown that the dog food did not actually contain the probiotic species listed on the ingredient label or if they did, it was in very low numbers.

Your best bet is to feed your dog food that contain naturally occurring probiotics.

  • I was told to stop my 7 month old german sheperd puppy eating fecus to give buttermilk (probiatic) will help stop this. And vitamin b could also be given and if do how much?

  • Many discourage giving dairy products to dogs because they may be lactose intolerant. Buttermilk is lower in lactose than regular milk, and it does contain bacteria that may help the digestion of lactose. … Start small, and if your dog likes it and tolerates it, then it ought to be okay.

  • My dog has had a history of allergies. This year her allergies were about the worst ever in 10 years. We have tried everything from allergy meds getting the leisions she gets biopsied. Finally got a blood test done and sent out to California where they somehow narrowed it down to 12 things she is allergic to, and in turn mixed up a medication which we give by injection once a week.

    Back to the original question after so many bouts of these allergies over the years and many different antibiotics ordered, along with medicated shampoo, soft stools are always a problem. I have found mixing boiled chicken with white rice and pumpkin and a teaspoon of plain unsweetened yougurt always did the trick.

  • I am mystified as to the reason my dog has blood coming out of his butt after taking a crap in our yard. It comes and it goes. He’s already been tested for parasites and there aren’t any/ Also we were told to give him probiotics. I have a tube of this stuff to put in his food. He shows no signs of any listlessness or problems with his appetite. I did put a little cheese on top of his food yesterday which he loves and here there is this blood again. I am thinking back to when I first saw so much, and it was after I gave him vanilla ice cream to down one of the pills the vet prescribed for his problems. At first there wasn’t anything to write home to mother about, but about five days ago I felt sorry for him and let him have some vanilla ice cream in a dish. He devoured it, then came the next day where he had blood and diarrhea. I feel like a fool to have given it to him and now he is getting nothing but the chicken, rice and veggie mixture that he usually gets. Any comments on this would help us. I am making another vet appointment today to get this looked at as I am very worried about him. P.S. He has his anal glands removed about eight years ago due to severe infection!

  • My 4yr old German Shepard/ mix a rescue, no med history but has damaged lungs from supposed pneumonia s. We boiled chicken, cooked butternut squash +green beans, brown rice. Works well with suppliments for skin bones hair joints, but now he’s got diarrhea and throws up globs of gunk, he’s always doing this half cough over n over, that’s a cue to do his business or want to go to bed, Its hard to separate that sound for any distress. He doesn’t bark, or even play w/a ball. He needs a probiotic ( always thought so but vet poo poo’d it, now back to using my gut! ) The taste of tart in cultures is a real turn off for him, he loves Swiss cheese, would that be what I’m looking for if so, how much? He weighs 60lb. He’s been sleeping and waking up with something to get out of his gut, mix of food and white puffy goo. We love him, were the first couple in his love that taught him about love and that he is very loveable, thanks for you and this outreach Ritamarie

  • reply to JOAN VOSS , my golden retriever had the same problem, turns out she was intolerant to CHICKEN which is exactly what i was giving her all the time, removed that from diet and , hey, all better. You’ve got to check all ingredients on the packet as chicken is in a lot of dog food even the gastrointestinal ones which she was on , shes now on Lukullus duck and lamb and doing fine. Hope this helps.

  • My dog had blood in his urine today. I need to know what I can give him until I can get him into a vet to be checked for a UTI? Or is there homeopathic way to treat a urinary tract

    Denise Bruns 1 year ago Reply

  • Hey for the urinary tract… Totally a way to help but still go to the vet. Google the vet urinary so for dogs if it’s still out check out the ingredients and nutrition facts and find something that is on par. It will help or buy the vet food. I went Purina naturals for my last pet kept him going at old age with re occuring in sections for like 5 years past when vet expected the worse I hope it helps good luck

  • I have a 5-years old yellow lab, I tried feeding probiotic rich dog food. But it upset his stomach after a few days. I probably need to bring him to the vet.

    • It is not unexpected for a dog to react like that in the first few days. However, we do recommend bringing him to the veterinarian as she/he will be able ascertain what may be going on.

  • My little chaweenie has had some type of skin condition for the past 2 years. She loses her hair, her skin gets crusty and a dark color, like elephant skin, and has a terrible odor. We bathe her and the next day she stinks again. She has been on antibiotics, Prednisone, allergy meds, has had shots, blood work, special shampoos etc. Our recent trip to vet she was given thyroid meds and apoquel. We are at our wits end. We have tried everything to help our little fur baby. This is breaking our heart to see her go through this. If anyone can give me some advice, I would appreciate it so much!!#lovemyfurbaby

  • That happened to my cocker spaniel, it turned out it was the dog food she was allergic to, after I spent a lot of money at the vet also on prednisone and other things to try to stop her chronic itching. I changed her food to nature‘s recipe and within three days she was back to herself.
