Help deter your dog from his unsightly habits with GNC Pets Mega Stool-No Beef Flavor Chewable Tablets Dog Supplement. Sometimes our furry friends want to eat things that they really shouldn’t and that includes their own stool. So, GNC Pets designed a supplement formulated to facilitate the deterrence of stool eating so your pal can be the proper pup he truly is. Plus, each tablet contains digestive enzymes to reduce stool odor! Suitable for all dogs, this supplement comes in a chewable tablet form and has a savory beef flavor that your furry friend will love!

  • Chewable tablets are easy to crumble up and disguise in your pal’s favorite food.
  • Formulated with a lip-smacking, savory beef flavor that your furry friend will love.

    junk skip this one

    By on Top 1000 Contributor

    I had very high hopes for this product considering that the manufacturer is reputable. They sure missed on this one. The first issue was that a quarter of the tablets were either crushed or a regular sized. So at the bottom of the bottle there is at least a half inch of pill dust. Send each tablet is a regular sized no telling how much the dog is actually getting in each dose. I had my dogs on this for 2 1/2 weeks and saw absolutely no improvement in their yard behavior. The bottle is now empty and the behavior has not changed so obviously this stuff just does not work. Save your money on this one firstly because it does not work and secondly because of quality control.

    Chewy does not stock FORBID which we have used in the past (with mixed results) so we tried Mega stool product. Seems like all the products in this category get mediocre reviews, so there is no magic bullet- Didn't work for us, but it must work for some dogs!??.

    No Eat Poo pills

    By on Top 1000 Contributor

    We put one of our dogs on a diet and he started looking for "snacks" in the yard. These pills have convinced him to leave the yard "snacks" alone. We give one to all of our dogs, one at each meal. Our picky dog won't eat them by themself so we wrap it in cheese. And I should mention the pills cause sulfurous smelling gas. The pills didn't cause more gas, one of our dogs is flatulent and the pills just changed the odor.

    Great Find

    By on

    I’m glad I tried this product because it solved two problems at once. I don’t really smell stinky Frenchie toots anymore like I used to. They still toot but not as bad. As for the poop eating I’m still watching and haven’t caught them doing it yet.

    Another strike out

    By on Top 1000 Contributor

    It was worth a try but sadly it didn't work for my dog. I've lost track of how many things I've tried and unfortunately, until something works, my fur kid can't be outside without close supervision because if I don't clean up the stool instantly, it becomes a snack. I miss the days of working outside while the dog plays in the yard.

    Unfortunately it didn‘t work at all for our pug. We are trying this for several months now, but it didn‘t stop her from eating her poop.
