assume it is good?
I buy these because I trust the GNC brand. 1 of my dogs will eat it voluntarily, the other one has to have it disguised in Fancy Feast Salmon cat food before he will eat it. I assume they work, not sure. I can't tell a difference. I feel better as a pet owner!

Been giving my dog this product since she became an adult dog. I think it's a very well rounded product. She's been on these vitamins for 6+ years now.

The dogs like it.
They didn't tell me it tasted any different, so I assume it's all good. ??

It did not do good for my 11 pound dog
My dog has irritable bowel syndrome. Once in a while, I would have to give her a probiotic and it worked fine for her. One day I ran out, saw this GNC product and made the purchase thinking the prebiotic would be good for her to have along with the probiotic that was mixed in. Her problem persisted throughout several days. I thought I was going to have to take her to the vet and that she was going to be leaving me soon.

So, I decided to cut the chew in half. Things got a little better with her but still not good. Then I just took her off of it altogether and now everything is back to normal.

The back of the bag says 1 chew for 11 pounds to 50 and it says a half chew for 10 pounds and other. I do not know what it was but it did not agree with her. While others have good reviews and I'm glad, I still wanted to post so that people can take what I've said into consideration.

Needless to say, I will just keep giving her a probiotic.

my kids love it.. I just wish the large bottle came in the chicken flavor as have a couple of dogs that I have to crush it as they are finicky eaters and don't like beef. They don't eat dog food as it made them all fat.They eat chicken breast, pork loin and veggies and now I know they are getting all that they need to be healthy.
