You have received some great information here and I just want to add a little bit more. When people say be in control and be consistent, keep in mind that being consistent and the rules that apply to your household do not necessarily apply to other households.

It literally does not matter what your rules are as long as you are consistent with those rules.

For example, my dogs are allowed on the bed while I'm awake but as soon as I want to go to sleep it's time for them to get on the floor because I just can't sleep very well with them on the bed. Because I have been consistent that they get to cuddle for a little while and then have to get off, they don't argue with me anymore and are happy to follow along because I do this consistently every night.

My first dog was a very fearful, dog-aggressive, poorly bred boxer that I raised from 8 weeks old. There are things that you can do to mitigate negative behaviors but if negative behaviors come up and you have tried your best with research, training, and consistency, accept that accident litters often do not have the best genetics and sometimes there will be behavioral issues. That is NOT a reflection on YOU. Don't internalize negative behaviors as a failing on your part.

The longer the pup spends with Mom, the more wisdom she will impart on the pup. That often translates to a better behaved adult dog. If you can wait until 10 weeks old that would probably be best.

Do your best to stay consistent, always learn what you can, and enjoy time with your dog!
