Is it safe for a 3 month old puppy?

This product is safe for puppies that are at least 12 weeks old.

How long before we should see any results?

The length of time until desired results are achieved is dependent on each individual situation. We would recommend consulting with your vet about a behavior modification program to attain faster results.

Nope, sorry Chewy sad to say but it doesn't work.

Well I’ve tried just about Every kind of “Stop the Poo eating” supplements and this was my last resort. And I even gave it a good try too and went through 2 bottles

Well I’ve tried just about Every kind of “Stop the Poo eating” supplements and this was my last resort. And I even gave it a good try too and went through 2 bottles of it, but it still doesn’t work and it was an Expensive experiment too! BUT, there’s good news & bad news. The good news is that a Holistic Vet told me about a product called “Potty Mouth” and IT WORKS!! It’s a powder that I sprinkle into my dogs food when I feed them. Unfortunately the Bad news is Chewy doesn’t carry it yet. Come on Chewy PLEASE start carrying this product! It really does work, it lasts longer than other products, it’s less expensive than the other products and IT WORKS!!!

So good

This works so well my puppy doesn't eat her poop anymore. I give her 1 a day because she is so small.

Ease of getting Max to take this medication!

This medication has all but stopped Max's heart murmur from progressing for several years!

My dog thinks it's a treat!

I have had my dog on this for years. She may be over her "issue" but she sees this more as a treat now so why take the chance. They work and she loves it!
