About This Item


  • Concentrated live cultures aid digestion and modulate the immune system for your fur baby. Probiotics may help prevent urinary tract infections, and can even reduce allergic reactions by decreasing intestinal permeability and controlling inflammation. Your pup’s stomach will thank you for taking preventative action!
  • Stress can cause a change in the pH of your furry friend’s GI tract, and that may cause a loss in needed bacteria. This product helps support animals in a variety of situations, such as birthing, post-surgery, antibiotic therapy, weaning, worming and traveling.
  • The powder may be sprinkled on top of your animal’s food to ensure easy consumption.
  • Give once weekly to dogs and cats as part of a healthy diet program, every third day to orphaned infants until weaning, or daily for animals on antibiotics. Probiotics aid in digestion while modulating the immune system as well as inhibiting the growth and activity of harmful bacteria, such as E. coli, Salmonella, and Clostridium perfringens, all while helping to prevent urinary tract infections, reducing allergic reactions and controlling inflammation.
  • For use on dogs, cats, exotic and wildlife mammals. Every animal can use a health boost from time to time!

Does this expire after being open for however long? Or does it just expire based on the expiry date that is printed on the bottle? (For example, some products have a shelf life printed on the label, BUT once opened expire 8 weeks after opening)

It is recommended to use this before the date printed on the bottle.

Would this help with diarrhea?

Picky cat even takes this

One of my cats hates anything added to his food, wet or dry, but even he will eat this mixed into his wet food once a week.

Most of products are fine

To my understanding, this is manufactured with an 18 month shelf life, so I'm pretty disappointed to have received something so old. only 2 month of shelf life remaining Every time I order Expiration date does not exceed 6 months. Especially a pound older than a small product.

Works for my cat

I tried this in comparison to the expensive Purina version for cats. It works better, I use less, and it costs less. My cat has unexplained loose stools randomly and this at least firms them up and makes it easier to clean up.

Not good for dogs

This product made my dog constipated after the first recommended dose. Was a waste of my money. I am now using plain Greek yogurt for a more natural probiotic

A life saver

My cat Celeste has Mastitis and she was a pregnant rescue that I had nursed back to health. No vets are currently taking new clients even if I had been there before with my other cat so when I had to get her on an antibiotic treatment thankfully I had this on hand which I had bought for my cat Luna. She's doing a lot better now and I recommend this product to anyone needing antibiotics for their cats.

Seems to make a difference

I tried this product out simply to add probiotics to my kitty's diet. He is completely oblivious to its presence in his vittles. I don't quite give him the full dose - just a half teaspoon three times per day. However, he seems to have fewer tummy troubles, i.e. he farts a lot less! This is something I will continue to use.

Amazing stuff

I have used this medicine and brand for many years. So glad chewy has it. I use it for orphan animals ,sick animals, and recently my dog that had serious reaction from dog food I bought on chewy. This medicine got his serious stomach issues back on track.he has food allergies so this helps him to. I always keep this on hand.

Healthy Gut

My pup has a weird gut and I have tried different diets, i.e. removing certain foods, fewer treats, herbs, etc. I was pleased to find this probiotic that is just itself. She has 3 spoonfuls (provided in the container) in her breakfast. She has shown progress and is a much happier pup.

Great for all my pets. If you're doubting, try it!!!

I love anything that I can give to All of my pets and will last me a while like this. With 2 medium sized dogs and 2 indoor cats I want to do everything to keep them healthy, but at a reasonable cost. I had heard about this in the past but never tried it. I regret not trying sooner! My dog had reoccurring UTI's and had multiple rounds of antibiotics at the vet with little result. After the last round of them, I put him on Cranberry Relief chews and the bene-bac (as well as neutering him helped, check with your vet!) and he has gone back and gotten the all clear. Vet said he's looking great! I will continue using this for all my pets. Also, a great thing is they all love it and will eat it mixed in wet food.
