Some people have really twisted agendas... They believe the fallacy that breeding puppies is a "get rich quick" scheme and the ones who suffer for it are the animals! I used to try to explain to people like this that the expense of having a litter (and doing it RIGHT) should eat up most of whatever profits they're planning for... if a breeder breaks about even (with maybe a little extra for their efforts) they're doing it right... if someone throws two dogs of different genders together and doesn't do any testing, vet visits, purchase good quality food, etc... then, yeah, unfortunately they'll probably make some $$...

And, of course, they're probably thinking "the sooner the better" in your specific case...
I agree with you 100%.
(probably i'll be judged by this part...but i'll say it anyways)
We had a female toy poodle at home and i bought miniature male poodle... we didn't get them fix soon enough and one day...[ .......... :scared: - you know what happened]. I'm sure that if we had fix them, she wouldn't have been pregnant; but either way, there were puppies on the way...
I got over-prepared (according to my vet); he was in shocked how much i know and all the things i done and bought for that moment.
As prepared as you are, there is a lot of money, a lot of risks, and consequences from breeding dogs.
At the end, everything went well, but i wasn't able to sell the pups (not that we were planning on doing it). But i was horrible to me just the thought of "selling" "my babies" to someone and not knowing how they are and if they are treating them right or just as good as we could.
So, we kept them and we have 4 dogs now; and we adore them!
My point is, i learned my lesson and got them fixed but i would NEVER, EVER in my life see my dogs as a "puppy-machine"...
