Aww, Diana! Everyone has such good advice here! I know how you must feel having bought so much stuff for a girl (I was so impressed that you were so organized, LOL...of course, we bought Max when the opportunity presented itself and didnt' really have time to plan, but still.....we had to go to the pet store to buy him his first toy the day we brought him home!). I bet that you could return at least part of it, even if it's just for store credit (b/c if you got a boy, you'll still need all of it for him too), or like someone else said, it's brand new and you could definitely sell it here!
I got Max and always wanted to get a little girl friend for him, but the timing was just never right to get another puppy, and we went back and forth about was it "fair" to Max after being the only "child" for 3 yrs.....and then Madison appeared. He's 2 yrs old, obviously NOT a girl, but I can tell you that it would be hard to find sweeter, more loving dogs than these two little boys
. Max was from a litter of 3 and the only male; one of his sisters is extremely shy and sort of introverted (but she ADORES her mommy!!!), and the other one is just like Max; a little character. They're all so different with their personalities that it's hard to say. I think I would just say not to rule out a boy just for being a boy.....from what I've read here, it sounds like the boys are on the whole, a little sweeter disposition. When I raised birds, I can say for sure that the males were almost always much sweeter and even tempered than the females.
On the other hand, before I ever got my first bird, I wanted a cockatoo so badly and I couldn't afford to just go out and buy one when I finally had decided on what I wanted, so I kept going to an exotic bird store, looking at the smaller (cheaper) birds, thinking I'd just get SOMETHING that was feathered. But the store's owner told me "Don't just get any bird just b/c you want to have a bird. Wait until you can get what you really want, b/c you'll never be really happy until you do".....I followed his advice and the opportunity arose for me to buy my first cockatoo.......I was SO glad that I waited b/c I got exactly what I wanted and felt like I'd died and gone to heaven. Later on I got smaller birds, and loved them too, but it's only b/c I got what I really wanted from the beginning. So, I think you need to go see the dogs in question and see if either of them make you feel that way. Good luck to you sweetie; you'll make a great Yorkie mom!
