No dogs eat grass when they have a stomach ache. Its sort of like how we eat salt. You should only worry if you have chemicals on your grass.
I was always told that dogs do this as a form of Medicina,But in puppies they will chew most things.
It eats grass because it has a sick stomach. It want hurt your dog. My dog eats grass when his stomach is upset.
No its actually health.they eat it when thay have constipation or there stomach is hurting.
