Thanks so much, everyone, for your input! This is why I JUST LOVE this place!
I'm not struggling by any means, I just know that we'll be making much more money, soon. I just know that I give Lillie my 100%, and I know I spend (more than I should on toys, clothes, treats, etc.) on her. Thats minus the health items, vaccinations, etc. thats mandatory. Knock on wood she has been one healthy little pup, but thats not to say that she won't always be. It helps hearing the costs of certain instances--I just need to make sure I'm prepared.
I just feel so bad for the little girl because she just adores being around other yorkies and I feel like I'm being selfish and depriving her.

Also, my fiance is hopping into the Air Force as a pilot in March and he will be away (off an on for training) for a whole year and a half.

I would LOVE more furbabies around (since I'm pushing 30 already and I don't know if we are going to have skinbabies) I treat Lillie like shes my child.
I'll probably keep reading on and weigh out the pros and cons! I'm sure I'll know when the time is right! Thanks everyone for all of your input!
