Hehe, love this question.
Start off with a baby shep! Personally, males are more... "wild" then females, BUT females are more hyper! But to be honest the males are a little more intelligent, females are just as smart but my boy learned to sit in a matter of minutes. My female took an hour or so. But that is your choice hun!
Now, HONESTLY I dont really live in a huge house. I have a reaaaally big backyard but my house is a normal sized home. Which is perfectly fine with my babies, shadow and apollo.
Leaving your puppy outside can be a little hectic. I mean, they dig.. a LOT. My pups tend to eat rocks so Im always on the look out. As long as its not raining, dont leave your pup out. They can get sick.
Pups are a lot of work! They are crazy, wild, hyper, funny, teething gets really bad at 3 months! Thats when it starts lol. Make sure you walk them DAILY! seriously cause if you dont im **** sure that they will run everywhere.
You dont need a protection dog. Show your dog affection and such and they will love you a lot.
My female pup shadow still gets jealous when someone tries to hug me ahaha.
So dont worry about getting a dang expensive dog lol!
