What exactly are you wanting from the dog?
To bolt rabbits?
To mark holes?
To catch rabbits?
Ive never used a terrier for rabbiting, as IMO it is a no no.
If you want it to mark holes keep it on a lead and let it see rabbits bolting into nets etc and it will soon get the hang of it. The other two options are retarded.
Its all fun and games sticking your pet down a hole til you lift a turf and the thing has suffocated in a tight spot.
If you want my advice, keep the russel as a pet and get a lurcher.
