Dog likes it
Flavor Name: Marshmallow & Peanut Butter, Size: Large
It wears faster on the longer side, my dog does love this, but 2 sides are not chewed as much.

Terrific! Much easier to use than Kongs and my dog loves it.
Flavor Name: Peanut Butter, Size: Medium
I like these so much better than the original Kongs. The large opening makes it so much easier to put peanut butter or cream cheese into it. Plus much easier to clean out afterwards. My dog also likes to chew it and play with it throwing it in the air after he’s done eating the peanut butter. Very sturdy - he chews apart stuffed toys but his chewing hasn’t damaged this at all. I highly recommend this product!

Great for strong chewing dogs. Entertaining too!
Flavor Name: Peanut Butter, Size: Medium
My black lab can destroy the toughest of dog chew toys, but he's not destroyed this peanut. I fill it with peanut butter, yogurt, pumpkin or apple sauce and freeze it. It keeps him entertained for quite a while. When the filling is gone, he leaves it alone or carries it around begging for a filled one.

Super cute! If you have one dog it'll last a while. If you have more than one...buy two.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This is THE FAVORITE chew toy in our household. We have two grown labs and a 10 month old mutt and they all love this toy. They got a variety of chew toys at Christmas and this is the one that they steal from each other. That said, they've definitely managed to kill it. It's well worth the money and it's held up well to heavy chewers but four months later and we're going to have to buy a new one. It's now a stub. They managed to break off all the marshmallows about a week ago and the stick itself is more like a chunk now but we definitely got our money's worth.

Lasting 6 months in! Great smell.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This actually does smell like marshmallows which is definitely more pleasant than most dog chews!! It has held up to our power chewer. It’s a bit heavy for our smaller dog but he manages and it’s quite funny!! It’s a bit hard but that’s why it is holding up. Would buy again if this one ever wears out.
