Why do dogs eat grass, and keeping grass weed-free
I'm worried because Juney and Trixie eat grass, so I'm reluctant to let anyone spray for weeds in my yard. My problem is that the weeds are rampant right now. I just talked to someone about doing my yard and he said that the reason dogs eat grass is because they need potassium and his vet told him to put his dog on either Eukanuba or Life Science. He said his dog does not eat grass anymore.
Can anyone advise me? I really need to get rid of the weeds.
