We’ve all been there. You’re out on a walk, you glance down and your dog isn’t beside you. You look behind and there they are, munching away on the grass like a cow.

But why do they do it? Are they craving more greens? Are they about to be sick? Here are a few common myths, and the facts behind them, to help you work out what’s really going on.


The myths

Myth 1: Dogs eat grass to make themselves vomit.
Not usually. Fewer than 25% of dogs actually vomit after eating grass, and fewer than 10% show any signs of illness beforehand.

Myth 2: Grass-eating means your dog’s diet is missing something.
Studies suggest that dogs on a healthy, complete diet are just as likely to graze, so it isn’t a sign you’re feeding them wrongly.

Myth 3: Dogs eat grass to settle an upset stomach.



The Facts

Sometimes it’s far simpler than that. Plenty of dogs just enjoy the taste and texture of fresh, dewy morning grass. So what’s really going on? The science is a little different from what you might expect.


Evolution: Plant matter turns up regularly in the droppings of wild wolves, in some studies making up a large share of them. One theory is that the fibre helps wrap around and carry out intestinal parasites, and our beloved companions may simply have inherited the habit.

The salad bar: We picture dogs chewing on meat and bones, but they are natural omnivores and enjoy their greens too. On a walk, grass is simply their very own salad bar, and they munch away because it tastes good.

Boredom busting: A dog left to their own devices with nothing to do may turn to digging holes and eating grass for stimulation. Keeping them busy with toys, puzzle feeders and training games helps keep their brains ticking over.


The biggest issue

Eating grass is often harmless, but there are a few risks to be aware of. Chemical fertilisers, weed killers and pesticides can be highly toxic. Slugs and snails can also carry lungworm, which dogs can pick up from grass and which can become a life-threatening problem. If you think your dog is showing signs of illness, please contact your vet.
