I have a little boy and he wasn't potty trained when I got him and he actually wasn't hard to potty train at all. I think it all depends on the puppy, some are easier than others...this sight has a bunch of great information and tips for potty training though so don't be worried! I'm sure you're little guy is going to be fine.
As to names, before I got my little guy (his name is Jaden now) I was considering Simba (because his hair gets so poofy on the front he looked like a baby lion cub! lol) Adoree (because I ADORED him) and Bear because I thought he kind of looked like a little teddy bear. I finally decided on Jaden as when I called that name he really seemed to respond to it and now I can't imagine him being named anything else!
Best of luck to you with your new baby and congrats on joining YT!
