Why does my dog roll in poop and smelly things?

4 min read Updated on October 8, 2026

In shortA dog rolls in poop, dead animals or rotting fish out of instinct: it is normal behavior that wolves share, even though nobody knows exactly what it is for. The serious theories: masking his own scent, carrying the smell of a find back to his group, or simply enjoying a smell that, to him, is wonderful. It is not about being dirty or defying you. The real issue is health: some droppings carry parasites.

What it often means

Pleasure: what disgusts us probably fascinates him, and he does it again because he enjoys it.
Masking his scent: the classic theory sees a hunter covering himself in local smells to get closer to prey. It has never been proven.
Bringing back news: a theory drawn from watching wolves, who may carry the smell of a find back to their group.
Covering a smell that bothers him: right after a bath or perfume, many dogs rub themselves on the rug, the couch or the grass.
More rarely, an itch: a dog who rolls and rubs everywhere, on anything at all, may simply be scratching his back.

Signals to read at the same time

The lead-up: he sniffs one spot intensely, stops, lowers his head and then his shoulder. That is the moment to act, not after.
What he rolls in: wildlife or dog poop, a carcass, fish, a treated field. The risk is not the same.
What he does next: if he eats what he rolled in, it becomes a digestive issue, and eating poop is a different problem.
His body while rolling: loose, wiggly and blissful is the normal behavior; stiff rolling with frantic scratching points more to his skin.

What you can do

Know the risky spots, like pastures, beaches and woods, and keep him on a long line until his recall is solid.
As soon as he drops his shoulder, call him in a happy voice and reward his return generously: the treat has to beat the smell.
Practice “leave it” at home with treats, before you need it outdoors next to a pile of goose droppings.
If he rolled, wear gloves, wash him with dog shampoo and lukewarm water, focusing on the neck and shoulders, then wash his collar and your hands.
Never scold him when he comes back: he would link coming to you with trouble and come back more slowly next time.

When to see a vet

See a vet if he rolls and rubs everywhere, very often, while scratching, chewing or licking himself: fleas, allergies or a skin infection are possible. The same goes if his skin turns red, flakes or smells bad after a roll, or if he swallowed what he rolled in and vomits, has diarrhea or seems lethargic. Think about parasites too: wildlife droppings, including fox and coyote droppings, can pass some to dogs and to people. Ask your vet for a deworming plan suited to his outings.

Frequently asked questions

Why does he roll right after a bath?

To him, shampoo probably smells strange and too strong, and the bath was something to shake off. He rubs on the rug, the couch or the grass to get a familiar smell back, often right before a burst of zoomies through the house. Pick a mild dog shampoo, dry him well and keep him in a clean room until he is dry.

Is it dangerous for him?

Usually not, just smelly. The risks come from what he touches: parasites in wildlife droppings, bacteria in a carcass, fertilizer or pesticides on a treated field. If he swallows some of it, his stomach pays the price. A quick bath and well-washed hands take care of most of it.

How do I get the smell out?

Wash him the same day with dog shampoo, twice if needed, working it in against the grain on the neck, shoulders and chest. Rinse for a long time: shampoo left in the coat irritates the skin. Skip perfume and essential oils, which can irritate or even be toxic. Fabric collars hold the smell, so wash his too.

Can I break the habit?

Rarely for good: it is instinctive and rewards itself. You can make it rare by planning around risky spots, watching for the moment he drops his shoulder and paying very well for a recall or a “leave it.” Some dogs barely care about it, others think of nothing else.
