Welcome to YT!
I have two morkies. One who got more of the maltese laid-back attitude and one with the hyper yorkie attitude! They are great dogs, and need a LOT of grooming! But I get them in a puppy cut every 2 months and it does them great. As for training, mine are SUPER smart learning tricks. Housebreaking...ehhh...not so much. One is 3 and the other is a 1.5 and they still puddle in the house occasionally. Even with that, they are the loves of my life and I couldn't live without them! Doesn't hurt that they are also so so cute.
Their personalities are all different, but a lot of it depends on how you treat them and train them. They focus their life around you, you know! You will enjoy her so much & she will be a blessing. Post pics soon! xx
