This was one of the first toys I got my dog and he LOVED IT. I sadly had to throw it away because he peed on it but this is something I will definitely repurchase. Perfect for tug of war and playing fetch. Definitely not indestructible as he did rip it a little but it took him a LONG time to do that

Remains a favorite

Color: Orange

This toy was perfect for my pup who's a big biter and most toys will last about 2-3 days. The material on this toy is very durable and remains the favorite with the crinkling sound.
