As I already said: Learn to speak animalish! Dogs will understand what you're saying by just raising or lowering your voice.
My couple of Golden retrievers follow a snip of a finger being one year old. Just have the time and patience for intense care of at least one hour per day. (preferrably 2 hours)
You don't necessarily have to run around with them (my stepdaughter can do that well), but you have to catch their attention and teach them anything you want.
Give them a goody only if they have deserved it. It's you to decide if they did or not!
Dogs always try to look good in the opinion of their master. Never forget about that. They need a "leading" (alpha) dog which has to be you.
Failing to be the alpha-dog you will never get the result you imagined.
