5mths old! Thats crazy, We are not talking red or horn now whin, so why does a rabbiting dog have to be fearless....
They need to first of all give you a good mark(one you have 100% faith in) Then be still while the nets are laid... Also be silent, Then work the warren on tip toes, knowing where the next rabbit will bolt. Not stick its head into the nets, and most importantly nail any bolters that have missed a net, then get on with the job at hand...and be good with the ferrets...
If you talking rabbiting dogs, as running them, well every lurcher i have owned has caught rabbits
