Despite the yuckky smell - these work!!!!
I agree with the other reviews, these chews are smelly - but my goodness, they work so well. My furry baby was on high doses of steriods due to a illness and these probiotics were recommended by my vet. Just one a day helps our dog stay regular - without runny stools, etc. They work great for our dog.

They smell so bad but work so well
the little individual wrapped squares are like little starbursts from Heck with a rancid smell of aged belly button funk, i had to find somewhere to store them because the smell comes out of the bag i have to half mine since my pup is right at ten pounds so hand washing is a must. He used to do little pellet poops and really strain. Now since his herniated disc injury i didn't want him straining so hard. He does nice long poops now with a lot less straining

You can smell it working!
They worked well for my dawg. Not so much for me. You get all the benefits of probiotics with the alluring fragrance of dead squirrel! After opening the package and digging into these individually wrapped treasures you'll be the center of attention to all squirrel carcass loving canines on your block.

Yes, they do stink but they work
I have 2 dogs with colitis from time to time. I needed a chew, not a tablet because one dog is a very finicky 18 year old. She eats these without any trouble.
Yes, it contains some sugar, however how else can one make gut germs taste palatable?!

MAy I return the two unopened bags?
My dog is experiencing Diarrhea. I usually give him GNC Ultra Mega Digestive Health Complex and he doesn't have this problem. Is there a way I can exchange my two unopened packages of the chewable for the tablets?

couldn't take the odor
This was a great disappointment because we couldn't order the tablet s anymore. You seem to be only selling the tablets through Petsmart at very high prices. There deals merely bring the price to what you used to charge. Very disapointed in GNC online.

Won't buy EVER again!
These things smell horrible! Just opening the bag makes me feel ill. Don't waste your money!

Had been so pleased with the tablets but they are discontinued. The new chews smell terrible and stick to the wrapper. They are going back.

Not only are the first two ingredients sugar and high fructose corn syrup, they smell awful. Don't waste your money. I sent them back I was so disappointed.
