6 is fine for now but I would LOVE one more! lol, but after I move that will change, my mom and I are moving to an acrage after I graduate, and I am going to breed(and rescue) border collies, I will have my own kennel, my mom though wants to breed as well, preformance dogs, she would be a totally different kennel though, and would not be related to mine in any way. of coarse I have to learn how to care for a flock of sheep before that lol cant breed border collies without livestock! not real BCs anyway lol
