Very good post that katchum and exactly why youll never see me advertising a litter of lurchers even if i did breed. Im pretty confident that somewhere out there theres allways a chancier litter than what i could ever put together myself.
Like yourself ill put up with certain faults or traits but only until something better comes along. And you only find better by pushing and testing until your atleast 90% happy with what ya got there will allways be abit of disappointment in dogs but its worth it when youve got an animal you can trust in for me it is anyway.
