Many people think that when their Chesapeake grazes on grass, it must have an upset stomach. Others, think dogs get upset stomachs because they grazes on grass. No one really knows why dogs eat grass and it appears there are several different theories on it.
What I can tell you about Chesapeakes is that they are grass grazers and one might think they are part bovine. Chessies eat grass all the time, and not necessarily because they have an upset stomach. Now, I am not saying this won’t cause an upset stomach, as many of my dogs have woken me up in the middle of the night with grass-filled puke. I’m merely pointing out that if your Chesapeake is eating grass, it’s probably not a big concern. Rather, they just like the taste of it.
