Dogs love it, but it lasted 10 minutes
Color: Blue Yellow, Pattern Name: Alligator
Five stars for the dogs both loving this thing. I have a Catahoula/pitbull and a Great Pyrenees/Red Heeler. They absolutely loved this toy but it only lasted about ten minutes before it was pulled apart and losing its innards. They didn’t really care - they each took half and proceeded to tear it to shreds with great joy. Two stars for durability, but since they’re big dogs who are happiest when chewing on things I figure the toy deserves to be rounded up from a three to a four. Small dogs probably would still love it without the strength to yank it apart so quickly.

Dogs both love it
Color: Blue, Pattern Name: Toucan
Dogs are obsessed with this, somehow has not been gutted yet. Long enough that they can both play with it. Neck not as stretchy as I envisioned but it’s fine.

Not worth the money
Color: Green, Pattern Name: Dinosaur
Thought it would be larger as it states LARGE-it was not- it is not interactive - also states that but it is not - so value for the money is not correct - not worth it

Cute, but short-lived
Color: Blue, Pattern Name: Toucan
Santa brought this for our 3-year-old sheepadoodle! Super cute, but she tore it up within a few days. We did like the stretchy neck! She had a lot of fun with it while it lasted.
