I wanted to share:
I thought that the bubbles that don't pop were a really cool idea, so I went out and bought some for Paddington. I don't recommend getting these for dogs with longish hair- When they do pop, they basically turn to goo and I had to pick it out of paddington's fur! It was a big mess.
It really is a cool product, but not practical for yorkies.... my preschool students love them, however!
