My 2 and a half year old male eats everything he shouldnt. I cant have balls to play with because he chews them open and start to eat it peice by peice. He chews up all his stuffed toys, eats and swallows the stuffing and then the squeeky toy inside. I dont know what to do with him. In the yard he eats branches off my trees that fall to the ground. He eats alot of grass, and sometimes he vomits. I just dont know what to do. Any suggestions?
