Do you know the hounds Health history the past 3 years

to some extent I look at hounds as Athletes . In this case it would be coming out of retirement

most will be able to remember the basics ,though YOU may have to do some retraining to YOUR style of hunting . The hound should be in its prime but you may have to spend some time to get it back in shape . I'd be thinking about 40% below his asking price . Hope it works out well for you.
