This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.

Surviving a 8 month old heavy chewer

Color: Blue, Color: Blue

My dog is OK with it but doesn't like it as good as the whale indestructible toy I got her previously. She chews on it a little while and quits. She acts almost like it makes her nauseated. Idk though.... It gets very very sharp! Be careful grabbing it after they've chewed it.
