Is this nondairy?
Answer by ChewyJan 15, 2018
This product doesn't contain dairy.

I have this for my puppy, but I have two cats, as well. I have been putting it in my puppy’s water in his kennel, but I was wondering if it would be ok to put in the main water in my house that both my puppy and cats drink.
Answer by ChewyJun 21, 2020
This supplement is specifically formulated for dogs and is not intended for cats.

Game changer !! best Pro/prebiotic I have used

My one Cocker has had soft stools from day one. I have had her about a year. No clue how long she had soft stools. After vet visit, meds, prescription diet, vet probiotics… nothing worked. Tomlyn was recommended to me by my neighbor. GAME CHANGER!! Solid stools after day 5 . I give one packet a day and solid firm stools. I missed a packet one day and she had soft stool by end of day. Next day after one packet solid stool again. No clue why she has soft stool but Tomlyn has made a change and I am happy to give daily. Keep this around for my other dogs when they have diarrhea and clears it up quickly in a few days.

Just the Ticket!!

I was looking for a reliable remedy for our older dog's gas. I credit this product with markedly improving family time. I mix it up in her water first thing in the morning, and I'd say it eliminates 90% of the problem. It's priced very competitively here, too!

great for upset tummies!

We love this stuff. One of my pups is unfortunately on a lot of medication, one of which really upsets is stomach. We add this and some hot water once a day (he’s about 30 lbs and gets once packet per day) and it has completely solved our loose stool problem. We use it daily and NEVER have tummy trouble now - even when they get nervous from long car rides! Love love love it.

Sensitive tummy

I decided to try this product after discovering that my dog needed to stay on a probiotic everyday as he suffered from frequent diarrhea that was not caused by his food. I was using another product but on discovering that it was going to be a permanent addition to his diet, I needed to find a cheaper solution and so far this product is providing the same results as the more expensive one. The only difference that I can see is that this one appears to be odorless and tasteless and dissolves very quickly into the liquid that I add to his food. He gobbles it up as if it wasn't there so I'm not concerned that he doesn't like it or he's not getting the full dose. Would recommend giving this product a try.

Not recommended

I bought this product a month ago, my dogs will not eat it. I've tried every thing, nothing works. So now I have 2 boxes of unusable probiotic

Keeping the Dixie Chicken healthy

This Pre-Probiotic works wonders with our Chihuahua, keeps her digestive system working well, and we judge her health a bit by her BMs. And without this med she is a mess. Thanks for the help Tomlyn!

Great for GI health

I've used this to support all my dogs digestion. Healthy GI means more comfortable and predictable potty times and better nutrient absorption!

excellent product, a necessity for good health.

I have been using this product for years with several different dogs and it is extremely effective and much easier to serve to picky eaters who turn their nose up at goat yogurt.

Not all pre/pro's work the same

I keep this on hand. I am a pet sitter/boarder and at times the dogs that stay with me come with issues or will have an issue while here. Age, breed and excitment are big part of that. This particular p/pbiotic worked wonders for a senior girl that was staying with me recently. She had lost her housemate the week before and mom needed to travel to care for her injured mother so this girl was all out of sorts! Mom had been bribing her to eat, after the loss of her housemate, with things like ground beef and cheese :( Let's just say, it got bad then ugly due the all the changes. There was a lot of cleaning up going on and I grew tired of the circus. I put her on a very bland homemade diet and started giving her a different probiotic in the eve, which did nothing to help. I switched her to this one and overnight she turned it around. Within a few days I had her back on her original diet without a fuss or any issues. We were all relieved! 5 stars!
