It's less then one week that you have the Heeler, it is going to take more then one week for your yorkie to accept the new kid, not because he is a yorkie, any breed when a new kid has entered their life there is an adjustment period, there is no time limit on this. Plus 15 lbs vs 3 lbs, that's a lotta puppy. Also both are males, has your yorkie been nurtured. Two un-nurtured males is looking for trouble, they will fight for dominancy. I would watch that 15lb baby near your yorkie, if puppy wants to play he could hurt that lil 3 pounder. I would allow the yorkie the safety of the sofa, he needs a get-away place. Time and lots of patience with your yorkie, again, never force the puppy upon the yorkie, when yorkie is ready he will seek out the Heeler. Now that you have both of them sleeping with you I hope you realize once you start something with a dog, any breed of dog you are creating a habit that may not be easily broken should a day come and you decide no dogs sleeping on the bed. Dogs are creatures of habit. If neither of your males are nurtured, I would consider nurturing one of them.
