Stool eating behavior also known as Coprophagia refer to dogs that eat both his stool and other creatures’ stool. This is a completely natural thing for dogs to do but is extremely disgusting and frustrating for its owner.
Coprophagia usually occurs in young and growing puppies. Most dogs will usually outgrow this behavior when you feed them a balance diet meal twice a day.
If your dog likes to put stool into his mouth, try these tips:
1. Ask your vet for a food addictive that will make his stool distasteful. Mixed the addictive into his food.
2. Alternatively, you can add a few pieces of acidic food such as pineapple and courgette into his food to create the same effect.
3. You can buy off shelf products like bitter apple and spray it onto his stool. His stool will smell awful to him.
4. Alternatively, you can spray mixed vinegar-water solution to create the same effect.
These methods seek to make his stool smelly or distasteful. This will discourage him from putting stools into his mouth over time.
If all the above mention tips failed, consult your vet for further assistance.
