I know which forum you are talking of, and I just want to say, don't take it to heart. I've "known" some of those people for a long time (we were all on another forum which crashed for a while). Those people are very nice and just want the best for you and for the potential dog. Many of them know what they are talking about because they show, attend shows or do lots of agility/obedience with their dogs. They study, work hard and find out all they can about different breeds. And alot of them don't see beyond what your typing because it's a forum, they don't know the whole situation.
Try to learn from it, I got alot of crap because I would post things on forums that I didn't know about and people would jump down my throat. I remember when first getting into rats years ago, I asked if I should breed my hairless because she was so hyper and I thought breeding her would calm her down, a TON of people nearly burnt me at the stake. Now I know why and would never DREAM of breeding anything because there are too many animals here on this world. But I didn't know then, I learned from it though.
Take what they say with a spoon of sugar, so to speak, when reading it. Sometimes it may sound like they are being harsh, but then again, you can't hear their tone of voice and they can't hear yours, so as long as no-one is bluntly calling you dumb, or insulting you, they are just trying to help you.
And please stick around the forum, we'd hate to lose a member due to misuunderstanding. There is much to learn there and mostly friendly people.
PS - I am Kelly on that particular forum you are talking about.
Also wanted to add, they are very picky on breeders and usually can tell a good breeder from a bad one (bad being a backyard breeder or mass producer), so let them help you with that, it's really hard to tell when a breeder is just in it for the profit, but many of them know alot more than you and I do about it.
