1. Too young to take from mom, unfortunately so...
2. Crate train. Crate train. Crate train.
3. Leave a leash on it at all times while in the house- so you can grab it and go outside quickly
4. Be wary of too much freedom. And by that I mean, leash training, eye contact (the foundation of all training) and recall need to start ASAP. Otherwise, the pup do what it thinks is best. And for, that usually is all wrong.
5. Practice operant/positive training techniques (google it).
6. Crate train. Crate train. Crate train.
7. Seek out a puppy socialization class immediately.
8. Get him out in public to meet people. Try to have him meet 100 people before he’s 16 weeks old.
9. Crate train. Crate train. Crate train.
I got my first real puppy (a Border Collie) in 15 years in April. He was 7.5 weeks old when I got him, and has been a dream, mainly because I’ve learned so much on training and now train others as well as rescue dogs. He loves his crate, loves people and other dogs, and has already mastered the basics as well as several tricks.
Trust me. You will get out of your puppy what you pup into him. There will be challenges, particularly the usual puppy stuff (chewing). But it will be worth it!
You have lots of good advice, and some not so good advice. Reputable breeders don’t let puppies go at 6 weeks. Crate train. Crate by your bed, get up when she whimpers, take her out, take her to the pee area on leash, stand there til she pees, say “go pee” or something consistently as she pees, no playing, back in crate. Maybe twice a night, then hopefully to once a night soon. She is too young to hold it very long.
Then during the day she should be contained to a small area — I like ex-pens to make a spot maybe 8 x 10 ft or so. Take her out to pee often, using leash, same spot, same words. By 12 weeks or so give her a bigger area, but always put her back in the small area when you can’t keep an eagle eye on her.
Also, lots of play time with ball, tug toy, clicker training to respond to name, sit, etc. This will give her mental and physical exercise.
Puppies are a big job and require dedication and management and a plan to train. Go online and watch some videos — Google Emily Larlham, dogmantics.com, great place to start.
4. about too much freedom -- the key point that my dog learnt as a puppy is stay and wait -- standing at the street curb for 15 minutes for her to learn that -- and then the second key point was "go" - meaning she's free to play (at the dog park)
I fully agree with puppy socialization -- in fact, go out of your way to have your pup meet as many dogs, as many varieties of dogs as possible (be aware of German shepherds, they attack puppies in my experience), plus goats, sheep, cats, horses etc. Also get the dog used to travelling by car, by bus, by train now and get her used to meeting all kinds of people - short, tall, white, black, brown, fat, thin, little babies, old people, etc.
