PS Even 1 litter per year is a lot for a breeding bitch, in my opinion.
I have lots of friends in the Ibizan Hound world and when their bitches title CH, they *may* have one litter in their lifetime.
Or they may never be bred at all.
In the 70s when Dobes were “hot’, a woman up the road bred a bitch my great-uncle gave her, to death.
Not to be dissuaded by that dog’s demise, she soon got another bitch and _bred her every cycle_ for about 2 years until that dog died, too.
They were the most horridly incorrect dogs I’ve ever seen but $35 a pup kept her in plenty of pocket money.
She also had a slew of little “designer dogs” in tiny cages on her back porch.
They just pumped out Malti-Poos and Cockapoos, month after month.
