To Yeti or not to Yeti
Set name: Yeti, Set name: Yeti
I’m honestly baffled. My dog Simba — a boxer, black lab, pittie mix with plenty of energy but not exactly a super‑chewer — received this Yeti doll on February 15th. Within days, he had chewed the hand clean off and yanked the rope straight out of the doll’s body. I expected at least a little durability, but this thing didn’t stand a chance. I’m still staring at the shredded remains wondering how it fell apart that fast. Definitely not what I thought I was buying.

Fun ball for my big Golden Retriever!'
Color: Orange, Color: Orange
It's big and has some weight to it in comparison with ither balls that hardly weigh anything. My 4 year old Golden Retriever can get his jaws around it only just! The squeaky is tough to get squeaking especially if you have a smaller dog. My dog is about 100 lbs and can just barely bite it hard enough to make it squeak. Very cute toy and I pretty sure this is going to last him a long time because it really seems very durable! He loves it!
