I am at a loss to find the safest chews for my Yorkie,Kiwi. I tried the greenies but she bit off the end and swallowed it whole-then started coughing. It scared me to death. Dingos-she chewed the end of and tossed it around her mouth. When I tried to get it from her she tried to swallow it whole. Natural pet chews-I bought some that were suppose to be all natural products-I believe they were made from animal parts-I will hold the chew for her but she gets so greedy she tries to bite a piece off and swallow it. I bought the larger ones hoping this would be impossible but in time she is able to disssect the chew. She loves chews and I hate to deny her of this pleasure but I am not comfortable with anything I have found so far. She always wants me to hold the chew while she is eating it so I am always with her and watching. I never leave chews around. When they get about half way down, I throw them away. Any suggestions? She makes me nervous because she is a little greedy and will run and try to swallow whatever she has if she thinks you are going to take it away from her. She is one year old.
