I guess it depends on how far down the rabbit hole you really want to go with this whole 'dog' thing. Keep in mind that your purchase decision has absolutely no affect on my life, so at the end of the day, do what
you feel
you should to do with the information that's been provided. I'll do my part in paying it forward by passing along what I would consider to be good information, just as I have received in the past.
I like to look at breeders as a game of odds. Odds are that by going with a reputable breeder, you'll have a better chance of obtaining what you want in your next family pet. They screen their dogs for health clearances, they back up their claims of talent and ability with titles or accomplishments, and typically possess a strong knowledge base on the temperament in that particular lineage.
Buying a good quality dog is by no mean a guarantee that the dog will turn out exactly how you planned (keep in mind that life is full of variability). I do think that when it comes down to it, you set yourself up with better odds when going to a reputable breeder than finding that easy puppy from the newspaper. Its a process, one that you
will get out what you put in. If you want a family dog with sound health and a good temperament, don't cheat yourself out of getting exactly what you expect. Don't settle for less because it seems easier (maybe I should make this a life quote?). It takes a lot of time and effort to seek out and find the things you desire, but if you go above and beyond what most would put out, it will no doubt feel a whole lot more satisfactory in the end.
My story:
I promised myself that my first german shepherd dog would -for sure- be from a proven and reputable breeder so that I could get all those great qualities I love about the breed in my new puppy. Three years ago, as I was getting ready to narrow down my puppys breeder, a 4 month old purebred German shepherd puppy fell into my lap at a local animal shelter (man, I won't even go there on how excited I was at the $ I saved in the adoption fee). Hey, she came with papers too

Now let me say, this dog has GOT to be one of the best looking gsds i've ever seen (for my tastes anyways) but holy crap has she turned out to be an emotional nightmare as an adult. I've got a psychology B.S., so naturally I take the nurture side of the debate. When I got my first GSD, I optimistically thought to myself that I could develop her into that idealistic, great, classic family dog that everyone envisions (you know, protective, stable, easy to socialize with, intelligent, obedient, etc etc).
Actually, no, shes nowhere close to being THAT dog. We did far more right than wrong with her, and with little to no improvement three years in, i'm now convinced she has this genetic hold of neurosis and weak nerves that going to be impossible to overcome. I've tried every fun socialization trick in the book and this dog still quivers and has a friggan nervous breakdown anytime shes even in the general vicinity of an obedience or socialization class. I tracked down her breeder a few months into owning her and again, great people with good intentions of breeding their nice looking dogs for family pets. Unfortunately in this instance, the result of their ignorance on good breeding practices was an
epic failure in temperament. Shes very dog aggressive and reactive to any stranger she comes across. She is a total CLOWN with me and my close friends/ family, however is a major liability around anyone else. It doesn't make me feel good that my stupid dog lunged at a five year old for running past us on a walk last week.
Guess whos got that nutbag living with her for the next 10+ years
. I'll be honest (everyone be nice), I often regret getting this dog. Don't get me wrong, I love her and shes a fantastic house pet. Shes apart of my family now and of course that won't ever change. Unfortunately, though, we got caught up in the moment, made an impulse acquire, and in the end, ended up with something we really didn't want.
Now, fast forward three years and I took another initiative towards finding
that dog I originally sought out. I had a list of things I wanted in a pup and took my time to research the breeders I felt could provide me with what I was looking for. Sure, I flip flopped back and forth between WHAT it was that I wanted, because I knew I didn't need the Ferrari of pedigree dogs (as everyone was insisting) but I also didn't want to settle for some crappy backyard bred dog again. I found a breeder, by chance, who really isn't one of those 'big names' but had great dogs and most importantly,
a super solid knowledge base. He was able to effectively articulate WHY he did that particular breeding and WHAT he felt it would produce. He wasn't in it for a quick buck, but rather had a genuine vested interest in developing and enhancing the german shepherd breed as a whole. Never did he try to sell his dogs, but rather, his dogs sold me. (BIG difference, one that you can only experience to understand). I drove a 14 hour round trip and almost vomited when I handed over 1500$ in cash for a DOG.

Now that i've got her, I would have paid 15,000$ for her if I had to do it again. There's just no comparison between her and just about every other puppy i've ever come in contact with. Truthfully. Shes a
baby at this point and even still, she walks into every new situation like she owns the place (super solid nerve base). Gun shots, firecrackers, sirens, and large crowds; this dog has NO hesitation whatsoever. At this point, I can't even begin to emphasize just HOW important and influential genetics have been on the temperament outcome of my two contrasting dogs. The puppy's temperament is becoming everything I had ever hoped for and though I'm loving the puppy stage, I can't wait for her to grow older and see what she becomes as an adult.
