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.
