Puppies are usually weaned from their mother's milk at 6-8 weeks (if they're lucky). I got Jake at 7 weeks. He was a handful! I adopted Addie from a shelter at 3.5 months. I have to say that the younger the puppy, the more work it is going to be. Addie was housebroken immediately, slept through the night, and was past the puppy nipping stage. She was easy to train. I know part of this is due to her personality, but age plays a huge factor. Jake, on the other hand, barked through the night for the first couple of night's, had to go to the bathroom 3 times during the night and every 30-60 minutes during the day, and had that puppy nipping problem. He needed me all of the time! He was a mere infant at 7 weeks. I can honesty say that having a young puppy in the house is almost like having a newborn child. Despite all the sleepless nights and chewed up belongings, my pups are worth it! I would definately suggest waiting until the pup is 8 weeks old, if you can. Whatever your decision, you'll have a friend for life .
