I would say my ideal pack would be around 3 dogs if I don't go into breeding, but if I were to breed and develop a full kennel I'd want around 6. Personally, I'd only do the latter if I had a SO or some fantastic connections to help me out.
I'd want a couple of Chow Chows. There's a woman in NH here who has Chows, and they compete in Agility. Because of a Chows thick coat, doing things in summer with them can be difficult, so if I got more involved in dog sports, like SA, protection work, or hunting, I'd like to have a Karelian Bear Dog.
So I guess my ideal pack is 3 Chows, and one or 2 Karelian Bear Dogs.
