Few things ...
If you think this forum is fanatical, oh boy, you've not seen anything yet when it comes to Dobes and their humans. We're the sane bunch. Hell, they welcomed me with open arms despite owning a mix (other forums would never do such a thing).
What we DO all tend to have in common is a genuine passion for animals. Several members do not own dobes. Some own several. Many of us own/have owned many breeds and species of animals. That's to say, a lot of us have been around the block, so to speak. I'm confident that had you asked about breeding ANY animal species, the results would have been the same. Because we care.
Profit. If losing money is out of the question, please, for the love of all things, do NOT breed. There are no guarantees with breeding and one minor issue can put any potential profit margin down the drain. An emergency c section, one ill pup - you will lose big bucks. And neither of those are "rare" occurrences even for the best breeders. That's assuming you even had a profit margin to start with, which is unlikely.
Idiot? No. But you have several members here with years, decades, some lifetimes of experience all saying virtually the same thing. Why do you think that is? It's not just because it's easier to go with the flow here. A lot of us have differences and we are pretty darn open about them. But we are all friends first and foremost. We may not always agree (really, head over to the political area ...) But we DO treat each other civilly and with respect, even if we disagree.
