Nope, that’s a negative

Chewy sells a bunch of poo-eating deterrents and the reviews for all of them are very mixed, so I wasn’t expecting too much. For the first two+ weeks, I thought

Chewy sells a bunch of poo-eating deterrents and the reviews for all of them are very mixed, so I wasn’t expecting too much. For the first two+ weeks, I thought it was working. She didn’t seem to eat any poop. As we used up the container, I was not convinced. My dog poops under a pecan tree and the nuts were falling. I wasn’t sure if she was going for the nuts or her poop (she loves pecans!). I reordered and discovered no, it’s not working, she IS still eating her poop. Oh well. I still think it was worth a shot to try, just wish I hadn’t reordered.

Hoping they work.

Well, so far it’s no go with Reggie. With all this snow, it’s hard to clean up, but we are vigilant and are out there as soon as they poop.

My dogs won’t eat these.

I gave it three stars because it’s obviously no fault of the company, but none of my three dogs will eat these. I’m not sure why they feel like stool taste better

I gave it three stars because it’s obviously no fault of the company, but none of my three dogs will eat these. I’m not sure why they feel like stool taste better than these supplements but thankfully, I’m not a dog. I guess I’ll try a different brand.

This supplement is in no way appealing for a dog. It stinks, it's a square brown nugget. I was able to get my dog to eat 1 and that wasn't enough to deter him

This supplement is in no way appealing for a dog. It stinks, it's a square brown nugget. I was able to get my dog to eat 1 and that wasn't enough to deter him from the nasty habit. He doesn't eat out of the litterbox, but he does from the outdoor flowerbeds where the strays I feed go potty. If I catch him in the act, he will drop it but I can't watch him the whole time he's outside, I would never get anything done.

No Poo didn’t work at all

I’ve given this to my Havanese every day since we received it; she still eats her poo any time she goes out to do her business.

I think it's working!

Tucker's got a nasty habit of eating his poop. I noticed today he didn't eat it. Keeping an eye on him when I can. Wish him luck!
