I really like buying Kong toys for my dogs. They tend to be well made, very durable, and my boys love to play with them.
I bought a Kong collar for Baby Ben. I expected the collar to be durable, just like the toys. However, Buddy (a beagle mix) was able to destroy the collar in just a few days. Now Baby Ben is running around the house naked, because he has no collar.
I was very disappointed with this purchase.
