I just wanted to wish you luck on your future yorkie
I got my first baby when I was living in an apartment, and we went on LOTS of walks, trips to the park and the dog park. It is important that they are not bored, because they can get destructive.
They can get very expensive so it is important to have a savings just in case for emergencies. We also have a couple large credit cards just for them because I want to know they are covered if anything ever happens. Some people choose to purchase insurance, but I find being diligent and putting away some money every month is more productive for me than paying someone else to cover my pets.
I wish you luck. I know that college students can be great owners, but a lot of younger people cannot handle the responsibility. I have now graduated and own a huge house and yard and could not be happier to finally be able to give that to my pups.
Good luck!
