Bought multiple. Still have a few in the package because the others are still going strong. Nice heft to throw them a good distance, durable enough for a heeler that is a very aggressive chewer to not destroy them after a month, and easy to see when they leave them in the grass. Good size, Good weight, Excellent durability, and keeps their attention longer than a actual stick.

Fun toy for dogs

Great toy for my dog. She loves when we throw it in the backyard for her and so far she hasn’t chewed it apart and she’s a big chewer. It’s bouncy too which makes it even more fun to chase. Great toy for the price

Great toy

Nice as a chew toy, fetch toy or for tug. My dogs liked it immediately. I love that it is not immediately destroyed, like most fabric toys.

Great for puppy gnawing!

I bought this toy a few months back and now I'm chiming in.. WOW! This is the FIRST toy our husky, Billie Eyelash, has NOT destroyed. She's about 16 Mos. and let no toy live this far except this one lol. I am amazed at the durability of this lil stick. When she needs to gnaw this thing is great! Gets right into the back teeth. They're is barely a mark on it and it's bouncy when you throw it. Yeah she loves it! 5 star
