I wouldn't breed mine until iam happy. And they done some proper season work under there collar.
Kat was 6 when she had her pups and star who iam breeding now as well 5.
But I don't just look at that as a reason to breed not just cause you got a good seasoned worker. The other factor is where the pups going. And who are they far.
I need another generation for me not interested in the money side as most only ever breed for money. It costs next to nothing to breed a litter maybe £100 at the most. Listening to these lot on here with the dogs fancy coursing names then they splash it on here
