Known as one of the best voiced noise sources to date, the Quantum Rainbow is a surplus of true randomness. Unlike digital noise which will only ever be pseudo random at best, analog noise is the only real source of natural random fluctuations. This is because analog noise is the actual sound of real

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)

The best bone you can get for pitbulls!

Size: Large (Pack of 1)

Can I give these more than five stars? Please?? They truly deserve more than that! I have bought these bones for the last 2 years for my pitbull mix, who is a very aggressive chewer. Her favorite thing to do is just lay and chew. These bones last FOREVER! She can lay there and chew all day long and they will last her MONTHS! It’s honestly amazing! These are the best bones we’ve ever given her and they are the only ones we’ll buy her! Not only do they last forever, they’re safe and natural too! Best product ever!
