Long lasting high entertainment toy
Style: Tipsy Rosé
I was gifted one of these for my puppy and it is a fabulous toy. I put in dried liver chunks with at least one that is a bit of a tight fit so it drags out the experience for him. It’s highly durable, gets dragged around and pushed under furniture, and shows tooth marks but is still very effective. I also appreciate it’s easy to clean.

Belgian Mal loves it

Our Belgian Mal LOVES this toy so much! She hasn’t destroyed it and we got it before Christmas. We put her cookies in it and it keeps her busy for about an hour

Not super chew material
Style: Tipsy Rosé
This is marked as a super chewer. But it’s super flimsy I returned because my dog would destroy it in seconds. If you have a super chewer don’t recommend this toy!

Excellent
Style: Bundle
These are so cute. My Chihuahua couldn’t pull them apart until I got it loose for him. A bigger dog may be able to do this easily. I think that is why he’s wasn’t too impressed with these. As a pet parent, they are a great toy. Extremely well made and excellent quality. Great value as well.
