Welcome!! I bet your baby Isabella is a cutie pie! Congratulations on being a new Yorkie owner
. It will take time (sometimes long) to potty train a pup, so a lot of patience will come handy. Make sure you socialize her but only after she had her puppy shots, makes sure that she eats regularly, being that small she needs to sustain the energy at a constant level... And, most of all, enjoy that puppy time because it will be gone before you know it!! LOL.
