Hi all, can I ask your opinion? I have 2 x 12 year old jacks. Ive had them from pups. I'm considering adding to our little family with 2 more jack pups. Does anyone on here have 4 jrts's? Is is that much more of a handful? If you did the same as I am considering, did you have any problems introducing pups to the household with older ones? Any advice, opinions would be appreciated please!
