Query: I do not recommend

I am very cautious about what I give my dog and always watch her carefully when giving her a treat she can chew. I am always worried about her choking on something. I heard everyone rave about greenies and decided to give one to my dog to try. She was 6 months old and I gave her a petite one for her weight (as the recommendation said). My dog is really careful about chewing her treats before swallowing. She really liked the greenie, but as was chewing it, the treat got really slimey, and a big chunk accidentally slid down her throat and she swallowed it. She then gagged and vomitted it back up. After the incident, I threw away the other greenies I had bought and never gave her another one. Now I have been hearing many incidents of greenies causing obstructions and it just re-iterates to me that I've made the right decision in not feeding them to my dog anymore!
