Personally though, I would stay away from a Working sire. Once they've started to chase rabbits, even if they haven't caught one, there still classed as workers and can be very aggressive after! My lurcher is from great showing stock, but when it see out pet rabbit, Fluffy, you can see him licking his lips, and I'm sure this has come from his dad chasing a rabbit once. Anyway we've called in a dog trainer/behaviourist so hopefully we can cure this.
