I've been a long time user of the blue flexible dental nylabones and I have never had a problem. I buy a larger sized nylabone so that it cannot be bitten off in chunks. I would rather use these than to risk byproducts like bully sticks that often harbor pathogenic bacteria / mold and are often of questionable origin from companies I don't trust. I also am not comfortable with natural bones after spending $1500 on a broken premolar. You're right that supervision is of the utmost concern, unless one is completely confident. My dog has access to his nylabones at all times and has for nearly 13 years now. I'm sorry that your dog had a problem and I am glad that all is on the mend. I hope you find something more suitable if your dog enjoys chewing.
