My dogs love eating grass, due to the food we are givin them they eat grass when we go out. Dont do no harm, they only eat long pieces an swollow to make themselves sick. its normal. What i did with my pup hes 7 months now, its a pain in the arse but find a small fence to start off with with no barb wire on top, an jump over it urself and encourage the dog to jump it, once hes jumped over, jump back over yourself a few times, its a pain i know but it does work, i did this with my dog an cause he was gettin the confidence on jumpin this fence, hed go over by him self when i asked him to. Hope t
