Shine bright!
Color: Golden
Shimmer is brilliant. It stays on longer if you add lotion to "seal" it in place. Small enough that it am not afraid it will hurt my eye if some gets in. Bonus that it has a refill. Bottle is super cute and glass.

Great toy
Color: Pawty
My dog loves this toy. I was pleasantly surprised to see it was a decent size for a stuffed toy, and not tiny. It seems pretty sturdy as my dog can shred some stuffed toys, but this one is still standing with the squeaker intact. The rope is securely attached within the toy and my dog likes to play some tug-of-war with it. Would recommend to other pet parents.

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.
