Like many people, I have spent lots of money on toys that say they will hold up against chewing, only to have my medium-sized black lab mix tear them up in minutes - he even chews through the solid plastic toys! This is the ONLY toy that he has tried to destroy but hasn't been successful. He now carries it around night and day, chewing on it quite often. He loves it and I don't feel like I have to watch him when he chews on it, nervous that he'll swallow a piece. Big fan of this product. Thank you!
