I think 2 is more than enough, how many REALLY can work more than one dog PROPERLY. . A good dog should handle 2-3 nights lamping, maybe a couple days ferreting+mouching. OK dogs get hurt, but a 2nd dog would cover that easy , till the other dog is fit.? Look at all the shit you have to get up, the feckin food bill for what,????? After all they are working dog's 1st, pet's 2nd. Ive had lurchers 25years, and i would rather keep 2, that work properly and do what there were bred for, than keep 3 etc..... and never see a feckin rabbit. [food for thought]
