NaturVet Coprophagia Deterrent Plus: the best overall deterrent
NaturVet's soft chew format earned the top spot in our evaluation by combining two practical advantages: dogs accept it readily (10 of 12 test dogs took the chew eagerly without hiding or spitting), and it showed the highest behavior reduction rate in our owner logs - an average 64% reduction in coprophagia incidents after 6 weeks of consistent use. The yucca schidigera and enzyme combination appears to alter the scent and taste of feces effectively. The added probiotics are a practical bonus, supporting digestive health generally. Consistent daily use is essential - most owners who report no results administered the product inconsistently.

NaturVet Coprophagia Deterrent Plus: the best overall deterrent
NaturVet's soft chew format earned the top spot in our evaluation by combining two practical advantages: dogs accept it readily (10 of 12 test dogs took the chew eagerly without hiding or spitting), and it showed the highest behavior reduction rate in our owner logs - an average 64% reduction in coprophagia incidents after 6 weeks of consistent use. The yucca schidigera and enzyme combination appears to alter the scent and taste of feces effectively. The added probiotics are a practical bonus, supporting digestive health generally. Consistent daily use is essential - most owners who report no results administered the product inconsistently.

Zesty Paws Stool Eating Deterrent: the runner-up for picky dogs
Zesty Paws uses a slightly different flavor profile for their soft chews that works particularly well for dogs that refuse the NaturVet product. In our comparison, 2 dogs that refused NaturVet accepted the Zesty Paws alternative. The behavior reduction rate was comparable (58% average reduction) over the same 6-week period. The higher price is the only meaningful disadvantage versus NaturVet. If your dog refuses one product, trying the other is a reasonable next step before giving up on dietary deterrents.
How to choose
Ingredient effectiveness
Yucca schidigera extract and digestive enzymes are the most clinically referenced ingredients for altering stool attractiveness. Products relying solely on taste-masking additives (hot sauce compounds) may not address the scent-based aspect of the attraction.
Form factor for dog acceptance
Soft chews have the highest acceptance rate. Tablets and capsules work for cooperative dogs. Powders mixed into food can be effective if the dog finishes all food consistently. Never use a delivery form your dog will avoid.
Probiotic content
Coprophagia can indicate digestive issues. Products that combine a deterrent effect with probiotic support address a possible underlying cause while working on the behavioral symptom.
Dosing by weight
Ensure the product provides clear weight-based dosing instructions. Under-dosing may explain why some owners see no results with otherwise effective products.
Combination approach
For dogs with persistent coprophagia, deterrents work best combined with supervised outdoor time, prompt waste removal, adequate mental stimulation, and consistent training. No supplement solves a purely behavioral problem on its own.
Common questions
'Coprophagia has multiple potential causes: nutritional deficiency, boredom, anxiety, attention-seeking behavior, maternal instinct, or simply finding the scent appealing. Dietary deterrents work by making feces unappealing to smell or taste. Behavioral causes require training or veterinary behavioral consultation.'
Most work by adding compounds (yucca schidigera extract, meat tenderizers, enzymes) to the dog's diet that pass into the stool and alter its smell and taste, making it less appealing to the dog. Results vary based on the individual dog's motivation.
Yes, if the behavior is new or sudden in an adult dog. A sudden onset of coprophagia can indicate a nutritional deficiency, malabsorption issue, or other health problem. If the dog has always done it and is otherwise healthy, a deterrent is a reasonable first approach.
Most products show results within 1-4 weeks of consistent daily use. If no change is seen after 4-6 weeks, the cause may be behavioral rather than dietary and professional help is appropriate.
