After the thread that Janabors started about the collars getting stuck I had never heard about it.
Today though we were outside in the sunshine and I tied the dogs up on a big rope and sat with them and the turtles.
We have a porch thing with slats and Olle was lying down panting.
I thought he was hot so I went to move him over to the shade and then realised he was stuck. His name disc had got stuck between the slats and because his legs are so close to the ground I did not notice.
It is a very good job I was there because he was pulling on it with some force.
