Responsible people do not "rescue" dogs and then breed them for profit… rescue is just that, finding a forever home... not making them cash "cows"... and then dumping them when they are not useful any longer. Doing better is not good enough.. doing it right is not about making money, it is about the breed, breeding health, well tested, socialized, well cared for pups that are part of the family from the beginning. Not raising them in kennel runs... Breeding dogs is a hobby, it is not a business... and as for "live and learn"... do that BEFORE YOU BREED, not during and after. Not hard to learn the right way... no need to breed 3 to 5 litters a year... there is no way that you can properly socialize that many pups, period.
And the answer to your question is "yes" I weigh my pups from the minute they are born, daily or 2x's daily if necessary. As do all responsible breeders... but they are also in the house, part of the family... not in a kennel... Sure there are many breeders that I do consider responsible and have kennel runs, but the litters are whelped in the house and the pups stay in the house... the dogs all get house time....
When this particular breeder joined the Forum they wanted to know about "how to cut costs"?... That is not keeping the best interested of the breed in mind
