I don't use a collar on any of my dogs. Last year while the dogs were playing, somehow my shorkie's teeth got caught on our yorkie's collar and we couldn't get him loose. He was wearing a safety collar and it didn't release. Well we almost lost Zach. When we finally cut him loose we put him on the table and he didn't move. We thought his neck was broken. Well I picked him up and he started to come around. We rushed him to the emergency hospital and Thank God there was no permanent damage. After that we took all the collars of our dogs and when they go out they only wear harnesses. They wear nothing in the house. If we had not been at home Zach would be dead. |
