Great quality! Sadie loves her dental bone!
Love all playology toys. Good for their teeth - vet recommended - and my shepherd can’t destroy them. She loves all her new playology toys we got her for Christmas!

Something “new” is not always an improvement
My dog has absolutely no interest in this. Looks like I fell victim to good marketing. Save your money and buy something your dog has enjoyed in the past. Something new is not always better.

Disappointed
It arrived on time and as advertised. I actually ordered 2 of the Playology toys and my boy did not like either. Total waste of $40 for the 2 toys. The toys are did not smell(to me at least) like the scent they advertised and my boy is sooooo food motivated and such a chewer that I was sure he would love these. Hasn’t touched them since the day I gave them to him. Very disappointed.
