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.

What color is the powder? How fine is it?
Answer by ChewyApr 22, 2018
This product is a white color and powder like texture.

Can this be used in a pet water fountain?
Answer by ChewyApr 12, 2021
It is not recommended to use this supplement in a fountain. When used in a fountain with a charcoal filter this product may be filtered out.

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!

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!

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.

I haven’t used it very long so I can’t really say yet.

Helps with food allergies

My dog has food allergies/sensitive stomach and tends to be pretty gassy. He can easily clear a room! I’ve tried other probiotics and they make him have accidents. Vet told me it could be ingredients used to make them palatable that he is reacting to and told me what to look for. So I tried these and we’ve had no accidents and have greatly reduced the gas! Glad it makes him feel better and more comfortable. My dog is 77lbs and I mix a packet and a half into his food. He eats it no problem

Great product

My Grandson’s poodle has had severe digestive problems requiring vet visits and special food. This product is easy to use I just sprinkle it over his wet food .... no more problems. He has gained weight and looks so healthy now.

Great product and works for dogs with digestion issues

I adopted a senior shelter dog who had diarrhea / loose stool for several months. I tried everything and even took her to several vets and after examination they kept advising me to change her diet/food which I did several times but nothing seemed to work. Until one vet recommended Tomlyn powder packets and told me to make sure I either mix it in her food, water, or both for at least 7 days straight. That finally stopped her loose stool problems. Now her bowel movements are normal but I keep these around as maintenance and mix it in her water a couple of times a week. I love that it's water soluble because there are times when she's picky and won't eat her food which is why I mix it in her water. I have a small 10 lb dog so I don't use the entire envelope. I use about half and it seems to do the trick. Very glad I found this product and would highly recommend it.

Made a big difference

One of my dogs started eating potting soil - a lot. I read that probiotics could help so tried this. She stopped eating the dirt so we are happy.

Have given a dose (based on weight) of this every morning after my pet suffered with diarrhea a couple of years ago. Now she rarely has any problem. She seems fine and laps this up when I mix it with water.
