I'm glad you are so happy with your dog and that everyone is doing well with him. How lucky that you are able to walk him 2 miles a day and that he house trained so easily. It's just great that you have had no problems.
That said, you got lucky. There is no such thing as a hypoallergenic dog, my dear, although there are quite a few with a single (vs. double) coat and which she less or almost not at all. And so you got lucky, that your husband's and child's allergies are not connected to the dog. You got lucky that the dog enjoys such long walks, housebroke early, doesn't need a crate, and has a personality that absolutely the entire word enjoys. It is SHEER LUCK and while I'm happy for you, it doesn't require you to be quite so self-righteous. You came here asking for advice, and you got it. Nobody was trying to create problems for you, just help you navigate the difficulties and weigh the risks, which is kind of what you needed. You didn't seem to know much about the breed, the 'breeder' or the issues involved in raising a dog. Hopefully (even if you won't admit it), the advice prepared you for some possibilities, or at least helped some other readers who might not have considered certain possible outcomes in their own lives (which of course is one of the main benefits and purposes of Mamapedia). If this had NOT worked out for you, what was your back-up plan, for example? Would you have given the dog back? Have you, and others, considered how traumatic it is for a dog to be re-homed? It's not a gerbil or a goldfish - it forms attachments and bonds, and when those are broken, it can be very stressful for the animal. So people with questions and risk factors (like allergies, lack of experience) need to be made aware of these things.
I, like others, spent a lot of time crafting my answer to HELP you. If you ignored the advice you got, that's one thing. But to come back here and slap people in the face with what Suz rightly called the "nyah nyah" tone, well, that was a huge mistake. I can't imagine that many people will consider you a supportive member of this community or someone really willing to think enough to help another member with a problem. I think you'll have a hard time getting help for any future concerns/needs you have, and I'm not sure that people like me will value your advice on any issues we might have. I hope I'm wrong about that, but really, can you blame me?
ETA - Just read your "So What Happened" - and I think it's very unfair to suggest that the members of this forum are driving people away. I think the surest way to discourage new members is to suggest in your post that everyone here is a nay-sayer and a Negative Nancy! That's a very unfair representation of the vast majority of Mamapedia members! Any new person coming on to read your post, thinking it's about dogs, would be quite dismayed to wade into this morass of blanket criticism. Any public forum is going to have a few people who are difficult, but painting the overall membership, many of whom have been on here for years, with one critical brush is really not the reality! I hope you will stay with Mamapedia, and that you will refrain from such comments in the future. Let's move forward, shall we?
