A replacement
This is a replacement for one my dog wore out after a year. This toy is great 👍 it is made very well. Our dog loves the squeaker and resists constant chewing. Lasted a year lol 😆

Somehow still squeaking
My dog is only a puggle, but he eats up squeaky toys like he’s a hippo. Somehow this thing is still going strong after several months of being his favorite squeaky toy!

Dog toy
Bought this dog toy for a tough chewer. It definitely works and isn’t getting chewed up. My doodle loves it. Picture is after months of use
