mine was 25 at the shoulder 51 lb in weight, she court rabbits other dogs would miss , hares for fun and roe no problem killing them before you got to her. she was also the softest mouth on bunnies, she wouldn't do fox however.
she had good feet , but like evryone else has said thin skin. im not exagerating when i say how intelgent she was . she had unbelivible eyesight and a brilliant strike, she picked up ferreting in a couple of outings would mark and of course take bolters.
she also wone the windmill cup in 2003 (doubled up coursing) and runner up in 2004. and then i lost her
