I purchased this product twice, and both times it was easily chewed apart. This creates a serious choking and digestive risk for dogs. Because of the potential danger to my pet’s health, I am requesting a full refund. I also believe this product should be reviewed for safety, as it could cause stomach damage or blockage if ingested. Please advise on the refund process and how this issue can be escalated.

My puppy loved it

Color: Black

It was perfect for her. It satisfied my puppy’s desire to chew on my tv remote. Definitely intended for small breed dogs though. As my puppy is not a small breed and as she has gotten bigger she has been able to chew off chunks of it.
