Case of Backyard Breeding in your own family?

Yeah I know a BYB, she's a family friend 1st it was Chihuahua's (properly sized) and her two dogs bred like there was no tomorrow, I'd say probably 1 litter a year for... maybe... 5 or so years and the only reason why she stopped those two was because her male broke his leg and now she is breeding a white GSD with a Staffordshire.
