Fun to toss
Style: 5 Pcs No Stuffing Basic
I was ordering another brand but bought this by mistake. These are FABULOUS. Not made cheaply some over twelve inches. My 40 pound pointer loves throwing them up and catching them. WOW.

Dog LOVES these!
Style: 5 Pcs No Stuffing Basic
My dog LOVES these toys. They are just the right size, have 2 squeaky toys - one in head and one in tail, which drives him crazy in the best way. The unstructured center allows him to shake them wildly and catch them mid-air. I will buy these again.

fav dog toys
Style: 5 Pcs No Stuffing Basic
The best dog toys. No stuffing all over the house! Perfect size for both our dogs to play with a tug of war with each other. My youngest dog is constantly bringing it to us to throw for her. It's got the noise to keep her entertained without being too loud!
