OK, so I'm sure I'm not the only perosn who has heard a handful of different stories of why their dogs eat grass. yesturday my mum's friend told her that the tips of grass are full of sucrose, so it's just like a sweetie for them. Ty also informed me his vet told him that it means the grass is giving the dog somehting that is lacking in the diet.. But don't dogs don't need sucrose(?). anyway! battle it out!
