Since all dogs are different, an individual dog’s nutrient needs are unique to their body. As such, results may vary. Consult with your pet’s veterinarian prior to use.

Ingredients & Use

Lactobacillus acidophilus, L. casei, Bifidobacterium lactis and B. breve in an enzyme-enriched substrate, extracted with water from a proprietary blend of three organic grasses.

Suggested Use: Give the recommended dose to your dog in water, add to their food or serve directly into their mouth. Can be taken any time of the day.

Store in a cool, dry place. This Liquid Probiotic is easily absorbed and, unlike solid probiotics which are treated with heat and chemicals, our probiotics are always in their raw state, ensuring shelf stability & maximum potency.


Q: I’m not seeing a difference in my dog when taking this. Is it doing anything?
A: Yes, yet you may not notice any difference. Most of these changes can be strictly internal and show results in blood-work or better digestion.

Q: Can I put the probiotic in my dog’s food?
A: Yes, the probiotics can be added to wet food or dry food. Some customers tell us they have success giving it to their dog directly. Whatever works best for you and your dog.

Q: Are the strains of bacteria in here the same as humans or are they for dogs?
A: Our Dog Probiotic has four strains: Lactobacillus acidophilus, L. casei, Bifidobacterium lactis, and B. breve. While this product is human-grade quality, these strains are the best suited for canines and are shown to maintain and enhance the natural microflora of dogs.

Dog Liquid Probiotic (4oz)

Dog Probiotic

I love the Dog Probiotic so far! I have 7 dogs.. large to tiny and I think they all like it and feel better!

Dog Liquid Probiotic (4oz).

Our two 13 year old German Shorthair Pointers are into their second bottle of the probiotics. We have noticed an increase in their activity level, playfulness, alertness & overall well-being.

Tummy Love

My sweet lab had to be on antibiotics for several weeks and was not tolerating them well, so I bought Mary Ruth's Probiotics for Dogs, and added them to his water between doses. He improved almost immediately - his appetite picked up and no more upset tummy. I will continue to add this to his water each day ~ he is a senior boy and this will help keep his immune system strong. Thanks Mary Ruth.

Best dog probiotic!

We started our 11 week old rescue on MaryRuth's organic liquid dog probiotic over her Canine Caviar twice daily and are so happy to say at just under 2 years old she is healthy and chock full of energy, has an amazing coat and sparkling eyes, super white teeth (she also has a redbarn naturals pizzle once daily) and her digestion is flawless! Thx so much for making such an awesome product, we're clients for life! 💚💜💙
