Today I was out with my dog for a walk, suddenly as he tore off his leash and ran away. This has happened before so I was not surprised. He is often rip off his leash when he sees a cat or a rabbit. He does it because he was a hunting dog before, so I think that his hunting genes are still left in him. Last time he tore himself loose, he was gone for three hours and I was looking for him everywhere, at last I found him at our house outside the door howling. That is why I worry never when he runs away I know he will always find back home.
