Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!

Buy it!
Color: Bacon, Color: Bacon
They love it! Very durable and a great squeaker that is seemingly indestructible! Definitely getting it in other colors, and impressed at the quality for the price. Don’t hesitate on this one- corgi and dachshund approved!

Perfect for young pups who get bored easily!
Color: Bacon, Color: Bacon
Our pup recently turned 1 and gets bored very easily, so she’s always looking for something new to chew or play with. We got her this little alligator toy and she is OBSESSED with it! She carries it everywhere and plays with it constantly. I’m honestly surprised by how durable it’s been considering how much use it gets. If you want to help save your furniture and household items from becoming chew toys, do yourself a favor and grab this for your pup!

Extremely durable but too large for our Aussie
Color: Bacon -Blue
This toy is very solid and seems like it would hold up well for aggressive chewers, but it ended up being too large and heavy for our Australian Shepherd. He had trouble comfortably holding it in his mouth and wasn’t very interested in chewing on it because of the size and weight.
The quality itself seems good, but I would recommend it more for larger dogs with bigger jaws that enjoy heavier chew toys.

Indestructible toy
Color: Bacon
This is a great toy. I have a husky pit bull mix puppy that can chew anything. I swear that dog can chew the varnish off a furniture. He cannot chew this up.I highly recommend
