Should I go to the emergency vet?

Grass eating by itself, in a dog that is bright and passing normal stool, can be mentioned at the next visit. Go the same day if the dog then vomits repeatedly, retches without producing anything, or has a swollen hard belly.

How much will treatment cost?

If grass eating has turned into vomiting, the visit looks for a foreign body, pancreatitis, or a simple gastritis. An injection for nausea and films of the abdomen are the line items to ask about before they happen.

Can I treat this at home?

Let a supervised nibble go if the dog is otherwise well, and keep lawn chemicals and foxtails out of the yard. A daily grass habit plus weight loss or diarrhea belongs on the appointment list this week.
