Grass eating is extremely common and most dogs do it at some point. Studies suggest the vast majority of grass-eating dogs are not sick beforehand and don't vomit afterward. For many, it's simply something they enjoy doing — the taste, the texture, or just the novelty of being outside.

Pro tip: Occasional grass nibbling on a clean, pesticide-free lawn is nothing to panic about.
warning When It Might Signal Something
Sometimes grass eating is paired with an upset stomach. A dog that gulps grass quickly and then vomits may be trying to relieve nausea. If this becomes frequent, or your dog seems unwell, it's worth a closer look at their diet and overall health.

Most grass eating needs no treatment. But contact your vet if the behavior is sudden and excessive, if your dog vomits repeatedly, or if they may have eaten grass treated with chemicals or pesticides, which can be toxic.
Pro tip: Keep your dog away from lawns treated with fertilizers, weed killers, or pesticides.
