Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.)
The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks.
Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.

Love all the Barkbox toys
Color: Christmas Consuela, Size: Large Dog
This is our third "Consuela"! Our dogs LOVE these toys, and they are the most durable we can find for our heavy chewers. They really like the ball inside as well. Highly, highly recommend these toys. I won't be buying other toys anymore, just barkbox.
