just dont be over keen as to letting your dog chase rabbits at an early age,hold it back til at least 10mths old just letting your dog watch the other dogs,then pick a few easy rabbits for it to run
I think giving them easy runs to begin with, not too many and ending on a high is more important than age tbh. Ok, I wouldn't start them at 6 months etc but someone new to the game could easily think as long as they don't run the dog until its a year old, its ready for a days work.
Best advice yet.When entering a pup.Easy runs are a must.A few close hoppers to start with.Will build confidence.
