Oh, suddenly having 11 puppies was quite an experience - it was wonderful and I'm glad I got to go thru it, but it was exhausting, and I wouldn't deliberately sign up for again. They all had their own distinct personalities. Their mom fed them and loved to play - but there's so much more to it than just that. I wanted these puppies to have the best possible chance at having a good life, and staying in their homes. I involved practically the whole neighborhood - kids and adults came over constantly to play, pet, and socialize with the pups. They were so used to people of all ages, men, women, kids, dogs (mine and my neighbors, who took mom and pups to her house on several occasions), and cats. They were used to noises - telephone, vacuum, radio, lawnmower, banging pots, etc ... so weren't jumpy when things happened out of the ordinary. They were used to different surfaces inside and outside - linoleum, carpet, matting, grass, dirt, rocks, pads, climbing on different things outside, small steps, all kinds of things - not to mention toys of all shapes and sizes. When they went to their new homes, they all came running to a clap of my hands and "come, puppies". They also would come running outside and potty to "potty puppies". No one could believe I could get 11 puppies to potty, but they did it!! Everyone got back to me and said they couldn't believe it, but the housetraining was 80% done before their puppies even got home. The two I kept had very few accidents (and they were my fault - I was gone too long).
No - the puppies weren't aggressive. By socializing them, I mean you want to get them used to as many life experiences (within your home) as you can before they leave. You don't want to send any puppy home at 8 wks who's only lived with it's mom, has never been outside, not met anyone besides your family, has been kept in a quiet room - and is basically clueless as to the outside world. I brought as much of the world to these puppies as I possibly could. I had a great vet, he did housecalls, and actually did "shot clinics" at my house. He came the night the puppies were born (thank goodness I didn't have to cart the mom and 11 puppies into the clinic) and checked the mom and all eleven puppies. Then, made several trips out periodically to check on them all, just see how they were growing, make sure everyone was healthy. He did their first set of shots - then held a "shot clinic" at my house for their second series, and everyone brought the pups back, we had a huge playdate/reunion, etc. Having picked up the mom out of the street, we had a huge bout of worms and diarrhea (I'm still trying to forget that - it was horrid) and he was treating her, so of course she had passed it along to the pups. I'll leave all that to your imagination, it wasn't pretty.
It was hard work, but I would have done anything for Brandy (the mom) and all her beautiful babies. You can also imagine the vet bills - they added up. The floor was mopped twice daily with lysol, everyone's shoes were either removed and left at the front door, or the bottoms sprayed with bleach before entering the house to keep from bringing in parvo or any other disease.
There are so many things, I could go on and on for days. I strongly urge you to find a book or start reading online about what to expect from a pregnant female, and then what to be prepared for once the puppies are born. Puppies go thru many stages, you need to know what to expect, almost day to day, if you want them to have the start they deserve. You need to start thinking about where you want her to have these puppies. Don't let her just pick a spot hours beforehand - you find the perfect spot, someplace quiet, safe, out of the way, where she can take care of her babies and get the rest she needs, also.
I meant to ask you also, do you have a vet appt for your girl anytime soon? You'll want to have her checked, make sure she's in good health, and have your list of questions ready for your vet - he/she can answer a lot of things for you. Since it's now been a few days, you basically have 60 days (or a few less, not sure when "it" happened) to get ready for puppies. It may seem like a lot, but it's not. Get going, you've got puppies on the way!!
