amazing cuddle toy
Color: Elwin
my dog’s fav toy at the moment. definitely not for hard chewers since it’s not durable. my girl loves carrying it around, squeaking it and cuddling with it. definitely worth the money, super cute and love how much my dog carries it around!

Our son's dog loved this non-squeaker! Very easy to carry around the house and cuddle with on his bed.

Very disappointed
Color: Enno
The toy was split into pieces in the first 5 minutes of the dog playing with it. Apparently not as durable as advertised.

Dog toys need to be sturdy - maybe you should sew them with a 5-thread machine like a serger?
Color: Elroy
My dog's full size teddy is disintegrating, so I ordered this one. It's very cute, but the seams are really weak. I've already repaired 3 seams in just a few weeks.
