Yes, as I think it does depend on how many bitches they keep - and how many people are wanting a puppy from that bloodline. I think one litter a year per bitch is more than enough - my girls were housedogs, and I used to take only 2, or possibly 3 litters in a lifetime (as in toydogs you might occasionally only get a very small litter). However, the motivation was to keep something in the ring, or to keep a line going, other folk could well have different ideas. Just spotted your reply Malka. Rather similar opinions aren't they?
