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.

My 2 German shepherds love these good quality last a good bit

Size: Large (Pack of 1)

I buy these for my 2 German shepherds. My male is a heavy chewer and he will spend time with this everyday until he starts to wear it down or makes it into a makeshift shank and I replace it Last about 3-4 months for aggressive chewers. Highly recommend (keeps them from chewing my stuff)
