I purchased soft digestible rawhide chews from my vet and smart sticks when Emmett was teething at about three months. All was well for about a month and then he swallowed a smart stick whole. As luck would have it - I had just stocked up. He loves the flavor. But since they made him really sick and it can't be good to swallow it whole. I wondered if now that he is older - 7 months do dogs have a gag reflex. I would love to let him chew on the chew sticks again.
