Well most hobby breeders are unlikely to be taking the maximum number of litters from their bitches anyway.
Just as an example I have a champion bitch who is rather sexually dominant and therefore not the easiset bitch to mate.
I tried mating her at 3 but she wore her maiden suitor to a frazzle and I only managed to get brief intimate contact, as she was a cow :rolleyes: Poor dog just wasted his efforts, as she would move at the crucial moment and leap all over him.
Tried her on her next season, and same game. Eventually managed to get her mated just the once to our imported dog just as she was going over and a litter resulted when she was almost four years old.
Tried her again 14 month later and she would not play the game. Next season after much messing about and pandering to her tastes in location and timing we got a litter nearly two years after the first.
She went 9 months before having her next season, and was now 6 1/2 and I wanted the chance to try an older champion dog who had only sired one litter, so I tried him with her even though it would only be a 9 1/2 month gap between litters, as another 9 months would have been too long.
In the event we got no pups, as he didn't manage to mate her until day 20.
I would never normally mate on successive seasons, but felt justified in this case because of the timing, and ages.
I am hoping she will come into seson in August (bit she might not come in until (november) when she will be mated and I hope have a third (probably last) litter before she is 7, as the first two were both by the same dog, and I want a male by a different sire to be available from her for future use on her daughters descendants from the first litter.
