Hmm. I probably missed something, but I thought you were getting an ACD mix pup? Oh well.

You probably dont care about my opinion at ALL, as I think you told me off before about my views on puppies and such ... but, I really do understand wanting to purchase a purebred pup from a reputable breeder. IMHO, even though rescue is saving a life, if it better suits you situation, it is NOT the responsible, purebred, dedicated, contract breeders who take back any puppy if/when it needs a new home who are pumping out pups that go straight into shelters. I absolutely understand wanting a very healthy dog from great parents who has been raised with lots of care & socialization.

If I were in your shoes, I would adopt an adult Lab, but that's me. It really is difficult to judge an innocent 8 week-old puppy as to whether or not they'll be kid-friendly, gentle, mellow, etc. My sister has a Lab (who she got as a tiny little puppy) who is now 100+ lbs and although he is extremely sweet, he could easily injure a small child because he does NOT know his own strength, even though he's 4 years old and matured. Anyway, it really is hard to predict a pup for your somewhat sensitive situation (as far as having a toddler, and living in an apartment, which both would not suit a very high-drive high-energy dog... sometimes, no matter how they're brought up). There is also the option of getting an older puppy/retired adult from a reputable breeder in your area. Lots of breeders need to re-home pups that turn out not to be show quality, or retired show dogs. Whatever you do, good luck! Either way, you are definitely committed, which is great.
