Hi, and welcome to YT. The members here are great & can offer you lots of help & advice if you do get a yorkie.
I can tell you that your boyfriend is right, yorkies have tiny bladders and are generally much harder to house train than larger dogs. Its also important to understand that they are very attached to their people, so it's not fair to leave them home alone for hours on end. I would NEVER leave a young pup home alone for more than a few hours because I would worry about their blood sugar levels. When they are adults, leaving them for awhile is not such worry.
Having said all of that, I would never be without a yorkie (or 4 lol). They are happy, loving dogs.
I rescued my first yorkies 25 years ago because no breeder would sell a puppy to me since I had very young children at the time. I adoped a pair of larger yorkies from the pound, and taught my boys to be very careful with them. Since then, I've always had rescue yorkies. I definately think they require more care and attention that most larger dogs, but they are well worth the extra effort!
If you do get a yorkie, spend as much time here as you can. you will get tons of help & support! Good luck in your decision! Lori |
