My GSP strikes again ....he eats like it is his last meal and he just does not chew any of his food. He is on Royal Canine which is the most expensive here, the kibble is the correct size for his breed and weight. I was thinking to get him a slow feeder bowl, would this help? He also threw up today and I think the culprit is whatever he finds he chews and eats. We are constantly using the command "leave it" and reward him with praise when he drops it out of his mouth however, he wants to chew everything like rocks, empty snail shells, tissue, sticks, wood etc.. it is becoming a nightmare on walks. When it is a big stick he holds it in his mouth and carries with pride which I think is adorable, but I could be the issue here and allowing him to do that whilst not allowing him to hold/chew other items. Any help would be amazing !
