đ¨ DOG EATING P**P? (Coprophagia) Yepâgross. Also common.
I heard this complaint constantly in practice: âDoc⌠please stop my dog from eating poop.â Fair request. Because nobody wants kisses right after a âbackyard snack.â
So why do dogs do this?
Sometimes itâs instinct. UC Davis researcher Dr. Benjamin Hart suggested ancestral canids may have eaten fresh f***s around denning areas to reduce parasite spread. Not charming⌠but possibly wired in.
A few weird-but-useful facts:
1. About 20% of dogs show serious poop-eating at some point
2. More common in multi-dog homes
3. Females are more likely than males
4. 92% prefer fresh stool (1â2 days old)
5. 85% prefer another dogâs stool
6. âGreedy eatersâ and food thieves are more likely to do it
When to look deeper:
Most cases are behavioral, but sometimes itâs linked to digestive enzyme deficiency, poor absorption, vitamin deficiency (especially B vitamins), parasites, poor diet quality, chronic digestive issues, excess hunger, stress, or boredom. If itâs sudden or paired with weight loss, vomiting, diarrhea, increased appetite, or a poor coatâget your dog checked.
The 3-step plan Iâd try:
1) Add a good vitamin/mineral supplement
Some dogs may be chasing a nutritional gap. One theory: thiamine (B1). F***l microbes can produce itâso a deficient dog may try to âget it from the source.â Lovely, right?
2) Try digestive enzymes
High-carb diets can leave partially digested nutrients in stool, making it more âinteresting.â Look for amylase, lipase, protease.
Start: Âź capsule per 20 lbs daily, mixed into food.
3) Make the stool taste bad (short-term)
Products like Forbid use an MSG-like ingredient. Not for long-term use, but it can work fast.
Amount: â
tsp on food daily for a few days up to a week.
Donât forget the basics:
Pick up stool quickly. Keep the yard clean. Walk after meals. Improve the diet (more protein, fewer carbs). Increase exercise and mental stimulation. And donât punish after the factâit usually just makes them sneakier.
