Ive been wanting to get a dog, But I have always owned just cats, Is raising a dog difficult? 
No, actually they are kinda friendly, I had a Yorkshire Terrier and he was nice
Arent Yorkies tiny dogs? I heard those are easy dogs to take care of, Whats owning one like? 
Yes they are relatively tiny their maximum size is like 8 to 9 inches. My dog was friendly to everyone, every neighbor knew who he was
Awwww that sounds so sweet, I bet I can fit the dog in a tiny harness and that would be adorable to take him on walks in it. Are there any other good friendly dog breeds that I can get? 
I used to do that with him hahaha. Other good friendly and adorable dog would be a Cocker Spaniel.
Oh yeah I heard of that breed, How big does a Cocker Spaniel get anyways? 
Well they look like Yorkshire kinda cousin, but with larger ears, a friend of mine has one of them and she's like 15 inches
Oh ok cool! I might get one then, What other cool dog facts should I know before getting one? 
Always pay attention to them, always love them and never let them feel alone, a dog (in my opinion) is better "person" than a human. They are so honest and they never let you down
