I just lost my dog of 14 years to a Dingo bone. She choked to death last night. I rushed her to a emergency vet clinic but it was too late. She was a Shih Tzu so beware if you have a small dog and you give them these. She ate Dingo bones as a treat all of her life and never had a problem. I have another dog and just threw out 4 bags of these. NEVER AGAIN WILL I BUY THESE for my dog.
