Our Annie was Carin terrier, she was one of kind, smart, but stubborn and alpha female. Carin's are prey focused. That why they can never be off leash in open area. They see prey they go straight for it and see nothing else not even freight train coming. The 18 years we had her she got off leach once and through hole under fence once. Luckily she didn't get hurt. We also had three yorkies.
