That exact same thing happened to some people I know. They were upstairs, and heard the dogs playing downstairs. The next thing they knew, there was some growling. When they went downstairs, they saw that Cayenne's tooth was caught on Cutter's collar, and it twisted the collar tight. When they cut the collar off, Cutter was dead -- they had to revive him.

Visa only wears her collar when she is supervised or outside. I worry about the gate unlatching and her getting out, so I always put it on her before she goes outside, just incase. She has a tattoo, but it's on her belly so someone might not see it, and she isn't microchipped because they don't check for microchips here. Collars are the best way to identify a dog here.

I'm glad that neither dog was hurt badly.
