This is good to know. I am trying to learn as much as I can. I have the property and the ability and sometimes one has to do something that adds to the world.
I also suggest you talk to breeders who have the breed you want. You will be able to tell right away who the hobby breeders are versus the conscientious. Stay away from the hobby ones.
If you're looking to turn a profit, good luck. Breeders quite often end up in the hole, esp. with large litters. Pups usually get dew claw removal by age of 3 days, plus all the shots/worming/health checks before they go home. Then there's structure evals from a top professional. And of course, what do you do with the pups who you can't find homes for?
There is A LOT that goes into this. Its not like opening a lemonade stand. :)
