Why do dogs eat grass?
I think that is a myth. Although sometimes dogs throw up after eating grass, they probably ate it because they were not feeling well in the first place. I have known several dogs who were simply "grazers" - in other words they just liked to eat grass. With a grass eater, though, you always have to be careful not to let them eat the grass in a public park or an any other area where the grass may have been sprayed with chemicals of any kind, whether fertilizer or insecticides or weed killer or anything else.I've always taken it as they are trying to make themselves throw up.
