Cute puppy. 8 weeks is probably too young to be released to new owner (for the puppy's sake). You really can't know the ultimate size of the pup at this point. Lot's of "breeders" (I'm being a little sarcastic here) use the term "runt" to market the puppy. By the time you figure out that the breeder was full of it - it's too late, you have a 12 pound teapot (that you love anyway.)
IMHO, I'd never buy a puppy based upon a "breeder's" assurance of size. I bet you that the contract for sale has a provision that there's "no guaranty" on size anyway. Also, letting the puppy be weaned so young should caution you.
I understand your desire for a puppy NOW!! I was that way too. I almost made a poor decision on a puppy. Finally, I got my wits about me, did a lot of research, took my time and found the right BREEDER & a wonderful puppy!
Best wishes in whatever you decide to do. Tracey |
