Same thing happened to Muffin with the Dingo. She LOVES to chew on the curly bully sticks but I ran out. I had some Dinos laying around that my Maltese didn't eat. I gave one to Muffin and she chewed on it for a long time and then I heard her choking in the other room! I was frantic...She had chewed off the end and it was logged in her throat!! My husband and I managed to get it out THANK GOD but I will never give her another Dingo - EVER!!
Muffin is a frantic chewer! She was going gonzo on Greenies and was even getting agressive when we would try to take them away. Needless to say she doesn't get those anymore either!
We love the curly bullly sticks. They are more expensive but they are better for them and not quite as dangerous.
