What Should I Look for in a Supplement to Stop Dog Stool Eating?

Before you even begin purchasing a a supplement to prevent your dog from stool eating, it’s important to consult your own veterinarian about your dog.

Seek Out Natural Ingredients

When purchasing a supplement, seek out natural ingredients that are safe for your dog. Some well-known healthy ingredients that prevent dogs from stool eating include yucca, parsley, and chamomile.

Do Your Research + Read the Reviews

Not necessarily the same, and be sure to do both! Research the brand’s reputation and where the supplement is made. Regulations for dog food, supplements as well as anything ingested by your pets are strongest in the USA, the developed countries in Europe, Australia, and New Zealand. It’s best to generally stick to these countries. In addition, read consumer reviews for product benefits, issues and insights relating to customer service.

Take into Account the Supplement’s Form

These supplements to discourage stool eating come in several forms, including chews, pills, powders, dry bits, and liquids. Chews or treats tend to be the easiest to deliver for you and your dog, since the dog feels like it’s getting a special treat. However, dog owners and dogs themselves have their own preferences and dogs may not like the taste of the chew supplements offered, so using a powder, dry bits, liquid or pill could be preferable.

One final point, it’s important to use any supplement consistently to combat a dog’s poop eating. It may take several weeks or even months to stop this behavior, so be patient and consistent!

Overall this product received fairly strong reviews and users found this supplement to be generally very helpful in eliminating this behavior. We do note that a more limited number of reviews on Chewy were more negative, generally with a decent number of reviews citing lack of effectiveness. Some of this lack of effectiveness might be due to lack of consistency and patience, as it take some dogs weeks or months before this product can be effective.

To Sum It All Up

The are numerous supplements on the market to help stop dogs from eating poop (coprophagia). As stated earlier, these supplements come in varying formats – chews, powders, liquids, pills, dry bits and liquids. We generally recommend chews, since they’re usually as effective as other forms and more user-friendly to give to your dog. For picky eaters, some of the other form of supplements – powders, dry bits – might work better, since you can blend them into food you know they already enjoy. Also, some of these supplements can help with a wider range of digestive issues. This can be helpful, if curbing a few other digestive issues simultaneously might be something you’re looking to do for your dog.


How do I choose the best supplement to stop dogs from poop eating?

Choosing anything that is ingested by your dog is an important choice. As we’ve stated previously, where the product is made is highly relevant to this decision. The USA, developed countries in Europe, Australia and New Zealand all have good regulatory standards. Researching the particular manufacturing facility and the amount of experience the brand has manufacturing is also good to know. Further, make sure the product is made of natural ingredients.

What is the best form of supplement?

Chews can be easy to use. Dogs are always open to getting treats, if they like the taste! But, if your dog is a picky eater and/or has any other digestive issues then a multi-supplement powder (or another form) of supplement may be the best choice for your dog. These supplements can best be mixed in with your dog’s food, which you already know they’ll eat.

How long does it take for these supplements to work?

It can often take weeks or even months for these supplements to work. Also, some work better for some dogs relative to others. The best approach is to have patience with this, usually you will see results. Dogs typically will often show less interest in eating stool (since the taste becomes less appealing), but sometimes they may not fully stop this practice. If you’re not getting the results you want though, consult your vet to discuss other supplement options or to better understand the reason for the behavior.
