Jackson eats grass all the time, LOL. He just loves freshly cut grass in the summertime.
He grazes like a cow, so do my dads dogs. There was only 1 time where I could tell his
stomach was upset, he was pacing, etc and he ran outside and ate grass the FASTEST
I've ever seen him and he had sooo much to make himself throw up whatever was upsetting
his stomach {smart!} So I do think some dogs eat it so they can throw up but most just like it.
