My dogs love these. I don’t put any paste in them. I stuff them with their dinner kibbles and then use something like peanut butter or bread on the ends to keep the kibbles in for a bit while they toss these and roll them around. Keeps them quite busy for a long time AND the best part is I have had 1 for months (and bought more) but this toy has stood up to hard chewing for as long as we’ve had them.

Total waste of money! My dog had the rope chewed off in 5 minutes and then started on the stuffing. Size was smaller than expected as well!

Perfect size for small dogs to play solo or gentle tug of war.

I ordered this toy for my dog. She is a 13 pound Shih Tzu mix The toy has nice soft fluffy, short fur and a mix of different textures that I feel when she’s playing with it helps keep her teeth clean. She loves the squeakers. She loves to squeak squeakers!! The tail is great for playing a gentle game of tug-of-war. I know she enjoys this toy because whenever she wants to play, she’ll bring it over to me and pop it in my lap. If I don’t respond, she’ll start pawing on my leg until I acknowledge her. Whether I throw it across the room or engaged in some tug-of-war, it keeps her entertained & stimulated. A great boredom buster! She’s been playing with it now for over a month and so far the squeaker still squeaks, and there are no holes or tears in the toy.
