Try a stag hound. They're basically just bigger greyhounds. More speed,bottom and harder bite on em. We use em for yotes but I'm thinking about breeding out a 2/3 yella bmc 1/3 stag. Greyhounds an stags r easy to find. U can buy here in oklahome for anywhere from 100 to 1500 bucks depending on a lot of variables
agreed in premise, buti dont believe stags are faster than track bred greyhounds, if they are then ill be shaving a few of them wooly boogers or trying my hand at some off track betting.
