How do I begin training my four week old puppy?

She may not learn anything at 4 weeks old. She shouldn't even be away from her mother until she's about 8 weeks. I'd give it a little time and when she's about 8 weeks I'd start trying to train her.

I had my toy poodle housebroken in 17 days. I'm not sure how smart a Shepherd is, but poodles are pretty smart. Here is what I did:

Take her outside every 1-2 hours. When you open the door to go out say "Outside. You have to go outside?" Keep saying "outside" then when you're out there say something like "Go pee pee" repetedly and if she went I'd say "Good girl. Peepee outside...good girl" and repeat it while you praise and pet her lovingly. If she poops I'd say "Good girl. Poopie outside...good girl." Repeat that too while you praise her.

Keep a constant eye on her in the house, I never crated her, but if she squatted to pee in the house I'd say, "No, Mollie." in a stern voice. Then I'd pick her up in the middle of it and take her to the door and say "outside" put her in the grass where you want her to go and say "Peepee outside. go peepee outside." Then when she finishes outside you praise heavily and say "good girl, peepee outside, good girl" Never scold, just praise. Keep doing that and the older she gets the more time you can put between walks, increasing by 1/2 hour increments.

As she got used to it I put a bell next to the door and when I brought her to the door I'd say, "You have to go outside" and I'd ring the bell and say "outside." Then I'll take her outside. I kept doing this for the last few weeks of training.

Believe it or not, she was fully trained in 17 days and she'll even run to the door and ring the bell and look at me. Then I'll say "you have to go outside?" and she'll wag her tail and run to the door and ring the bell again. I'll take her out and she'll do her business. I got her when she was 10 weeks old and she was completely trained by 13 weeks old and has no accidents in the house. She's 11 months old now and still no accidents.

Never use peepee pads or newspaper unless that's what she'll always be using because you'll only manage to confuse her when you change her routine to outdoors. You'll be teaching her to go to the bathroom in the house, then confuse her by telling her not to.

I work at home so I was home the whole time. If you'll be out of the house just have your daughter do the same thing that you're going to do and it should work like a charm. You should try this method. It's foolpoof. Good Luck!
