Sounds like your dog is enjoying his home-made snack! Here's a few tips we recommend at the hospital:
Pick up stool as soon as it comes out, need to be a bit more watchful.
For-Bid - all the hospitals I've worked at carry this product, you'll need to use it for a week or 2 so the dog learns to avoid stools all together.
Canned pineapple - You only need a small amount in comparison to the size of the dog to change the taste of the stool so they don't eat it. Too much can cause GI upset.
- Small dog (0-10kg) - 1/8th of a cup per meal
- Medium dog (11-30kg) - 1/4 of a cup per meal
- Large dog (>30kg) - 1/4 to 1/2 of a cup per meal
These tricks may stop working once you stop using them but don't worry! It is gross but not harmful for the dog to eat his poo and also NOT an indicator that he's ill or in poor health, he just genuinely enjoys eating it. I know some dogs who only eat their poo in the winter as it's frozen (poopsicles).
He may grow out of it as he ages, though not always the case. Some dogs will eat their stools because they are hungry as well, growing dogs need to eat more while some breeds are genetically predisposed to ALWAYS be hungry.
