ok mate a good jack Russell will push rabbits out for you no problem and they love it,also a spaniel or spaniel cross as they are a little more calmer i find especially after you have caught something(in my opinion) and dont usually go to ground,just take it out from an early age and let it see rabbits running about and after a while the penny will drop so to speak or get it out with an older dog, as for lurchers any cross as long as there not to tall would be useful, although something with a bit of whippet in will give the dog an early turn of speed but that depends on the type of ground yo
