My dog was bit by a rattlesnake a year ago. She has had stomach issues ever since. I have been able to find anything that will make her stomach feel better so she will eat regular meals. I was constantly trying to find the right kind of grass in the park that she would eat and that is the only thing that would make her stomach feel better. I have tried several other products and have been unsuccessful. This product comes in little cubes and I crush them up into powder and put in her food once in the morning and once in the evening. Not only is she eating normal again. But she is no longer just laying in the corner or waking me up at night with her obvious pain that she is been in with her stomach issues. I will continue to buy this product and I recommend this for anybody’s dog that has stomach problems. She does not need to eat grass anymore. I could not be happier.

She has much less grumbling and squeaking noises, less flatulence, and seems to be more energetic. I'm thrilled! She is bringing me her toys to throw repeatedly

She has much less grumbling and squeaking noises, less flatulence, and seems to be more energetic. I'm thrilled! She is bringing me her toys to throw repeatedly and moving around better. She'll be 12 Feb. '26. I love this product and the easy to dose nuggets.

They seem to accept it

They smell funky but the dogs 2/out of 3 take them the other one doesn’t care for them. I did notice their fur coat is changing to become very soft and I love that,

They smell funky but the dogs 2/out of 3 take them the other one doesn’t care for them. I did notice their fur coat is changing to become very soft and I love that, also they go to the bathroom just fine, no issues. Also gave some to my fur granddaughter and it’s helping her with the scooting

Works well

These worked really well and really quick. My dog was having frequent diarrhea and losing weight after drinking lake water when swimming. This helped him solidify

These worked really well and really quick. My dog was having frequent diarrhea and losing weight after drinking lake water when swimming. This helped him solidify and regulate his poops. I also started using it on my old girl because she’s been a little constipated and it’s helped her too. Both dogs really like them!

Seems to help stomach issue

Our little terrier would get loud stomach rumbling and would not eat for 24 hours. These probiotics seem to illuminate most of the issues
