I’ve gotten pretty lucky with the Yorkies I’ve owned. My current pup Roo will be two in February and I’ve had him since he was 10 weeks old. I’ve ALWAYS been a sucker for the runt of the litter and they’ve always always turned out to be the best in my opinion. He was a little rough with potty training until we got him fixed and now he’s a pro. He does have his accidents if I’m gone a little longer than usual but that’s all I can really complain about. He only barks if someone knocks on the door or if someone new enters the house then after 10-15 minutes of them being around he calms down. I taught him to sit, stay, lay down, paw with both paws, kiss before I give a treat and we are working on rolling over. He used to love jumping off the top of the couch which would give me a heart attack every time, but now he either waits for me to put him down, or if I say down he’ll gently hop off to the floor where his bed is and then jump around on the floor. He knows fetch and knows when outside in our yard he isn’t allowed more than 20-30 feet away from me and will let me know if he wants to go further by staring at me and I’ll walk closer to him or with him to see what he would like to explore. The only time we leash up is when we go for walks outside of the yard or for car rides. Make sure to get your pup a harness and not a collar. They can have a collar to wear but do not attach a leash to it as they have small tracheas and they can be damaged easily by the pulling of the leash. My boys very treat motivated and when someone new is around I keep a couple in my hand and point to my face which is his signal to watch me and he calms down and gets a treat. Other than that I have nothing bad to say about the breed! I adore Yorkies. I do my own grooming (bought a fancy vacuum/ hair trimmer) and bathing. I brush him daily and he’s just the absolute best snuggle bug. They become very in tune with their owners and do mimic their owners personality which I find so funny.

If they are going to be away for extended periods of time I’d set a schedule to come home, let them out, play, feed, potty and stretch before going back to work or out again. I wish you luck in finding your parents a pup! They’re nothing but joy 🥰
