Husky approved!
Color: Cheers
Got this for my large husky to wear for his 10th birthday. He didn't tear it up right away. The squeaker lasted longer than it does with most toys. He seemed to genuinely enjoy the toy. Removed the stretchy string once I got a few pictures so he wouldn't eat it. Very cute.

5 Stars - My Gentle Giant Loves It!
Color: Pawty, Color: Pawty
I got this toy for my German Shepherd, who is very gentle and loves soft plush toys. Even though he’s a big dog, he’s careful and enjoys playing gentle tug-of-war so the rope part as the string is perfect. The toy was a little smaller in length than I expected, but it hasn’t mattered at all — he absolutely loves it! It’s soft, thick, and has a squeaker deep inside that will make it hard for a dog to pull out. It is cute, and has held up well to a lot of carrying around and light tugging. If you have a gentle dog who loves plush toys, I definitely recommend this one. I would absolutely purchase it again! Fun little dog birthday gift.

Stupid cute!
Color: Crown, Color: Crown
My Lily looked so cute on her first birthday and it was so easy to put on. It doubles as a toy if you want to cut the band off. It's got a crinkling sound, no squeaker

Not for tough dogs who chew
Color: Pawty
My dog loves it! We play tug of war and it’s still holding up. She is 40 pounds and is strong. But this would not be durable for dogs who rip things apart.
