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.

Great toy!
Color: Elly
Great toy! Dog loves it and it is durable. We’ve bought other toys that he tore apart within a week, not this one! He takes it everywhere we go!
