[Help] Want a dog in the future, but am I too affectionate/lenient to be responsible?

I've had several dogs in the family growing up and I love them. Even when I visit friends their dogs are all over me and I let them because I love em so much.I want to get a dog of my own someday. My goal for my dog is for it to be my devout little loyal companion. I've been looking into getting either a Kai Ken or Hokkaido Ken as I've read these breeds are typically very loyal, energetic enough to play with, and are the size that I want (tired of lapdogs, I've always wanted a medium sized dog but nothing like a labrador).However, I've been interested in taking the whole dog owner thing to the next level: I want to try my hand at actually training my dog. I want it to be able to sit and stay and come when I call it, stop barking, etc, so I can keep it out of trouble.This is where I'm kind of uncertain. I'm really affectionate and not sure I'd be able to have both a well trained/well behaved dog and a dog that will snuggle me and jump up and down all excited when I get home from work. I mean I'd honestly probably do things like let it sleep on my bed with me. I'm not sure if this is a "responsible" thing to do if I'm trying to set myself up as his/her leader who's to be listened to at all times. Other miscellaneous things I'd like to be able to do with it include snuggling and rough housing and even picking it up completely (but I understand not all dogs like being picked up and if he/she didn't I'd not do so).Is it possible to have both sides in the same dog? I really want a companion in my dog, but it'd feel shallow if expressing affection would compromise its behavior/training. Or am I just overthinking all of this? via /r/dogs http://ift.tt/2sGeQOT
