Must buy!
Color: Grape
My dogs love this and so do I. It really smells like “fun grape” like a fun smelling marker. It’s gentle for their teeth and durable! They are both interested in it and take turns using it, pretty awesome!

Great for SuperChewers. Keeps my Golden busy.
Color: Bear, Color: Bear
My dog loves it and it keeps her busy for a while. She actually pulls it out of her toy basket and brings it to me when she wants it filled. I break her treats into some pieces that are easy to get and some a little harder. This way she doesn’t get them too fast or loose interest if they’re harder to get. Also, she’s had it for 3 months and there’s barely a mark on it and she’s still a puppy that chews her toys to pieces.

OMG- didn’t expect this to be my dog’s favorite stuffable dog chew, but it is!! This durable rubber like dog chew is still intact and smells like blueberries after over 2 months! Great for hours with each new treat! Am buying another, when I need to :) great value

Mostly happy
Color: Grape
Have a 1 1/2 yr old Belgian Malinois who needs things to do. I bought these and he loved it. Bad thing, it took him 1 day to chew the rope off both grape and pineapple. The stems on the cherry were also chewed off. The rest of the toy is intact and he still loves it.
