Crinkley Paper Should Not be Ingested
Pattern Name: Donkey, Pattern Name: Donkey
This thing was cute as can be, and for awhile my dogs got some good play time out of it. But I was somewhat mortified when I saw torn up pieces of the "crinkley paper" all over my living room carpet. It is like a crunchy Saran Wrap, definitely not something a dog should be potentially ingesting. They can say the toy is tough and durable, but it ultimately is not, so it matters what is inside it. I really can't believe they would put something like that inside a toy. As soon as I saw it, I immediately threw the toy in the garbage. All dog toys have something inside them that is pretty non-digestible, but this plastic seemed particularly wreckless to me. So cute or not, I cannot recommend this toy and will not buy from this manufacturer again.
