Yeah mate I can help you with breeding info. As for what the pups turn out like physically, well thats complicated genetics. They could look like any one of their relatives, more likely to be a mixture. Worker wise, if the parents are good workers, and the pups are trained right, they have a very high chance of being be fine workers like their parents. Even if the parents werent workers, a lot of pups, if trained right can be very decent workers, as lurcher work is based on prey drive which most dogs have anyway.
Firstly how old are they?
The bitch must be at least 3 before breeding.
