Well, Chloe is not all Chihuahua. So I can't be sure which of her traits come from which breed. But I will tell you what Chloe is like.
She is perfect.
Lol! But I'll give you a pro/con list.
Pros:
She's very obedient, and very aware of you and your feelings/moods/expressions. She knows what you're asking her to do, even if it's not something you've taught her. Like "get out" or "move". I've never worked on anything like that with her, but if I point out of the kitchen and say "get out" she'll go. Or if I'm walking through the room with something heavy and I say "move" she just...will.
She's always with me. She's not always right on top of me (if I ask her to, she's more than happy to be) but she's always in the same room as me and/or my sister.
She's great with other animals. She loves other dogs, is fine with cats as long as they're not outright mean to her, and is fine with smaller animals as long as I tell her to leave them alone.
She loveloveloves people. Amazing with kids, including babies and toddlers, loves people big and small, man or woman. I'd say she leans toward liking kids and women better, but I wouldn't say she's fearful of men at all. She just doesn't get as excited about men.
Her size is perfect for traveling. She's gone on trips with us and is a great travel companion. She fits in wherever we go and makes herself at home.
Oh, and she's adorable.
Cons:
She's very soft. I don't see this as a con exactly, but I know it can be for some people. She easily gets her feelings hurt, and can get depressed if harshly scolded.
When we first got her she would "pee submissively" if you bent over to pick her up or pet her. But that's nearly gone now, and she only does it every once in a while if you pick her up really quickly.
She does shed, but they're tiny little hairs that you hardly notice, and the shedding is not bad.
She likes to chase small animals if they're outside/unknown to her and I think if she was offleash somewhere and saw a squirrel, bird, cat, etc, she'd take off. She's usually very good about staying with us, and we don't worry about her when the front door is open, because if she steps outside, she'll come right back in with us, but I do worry that if she ever saw something, she'd take off. But because of her size anyway, I don't think letting her offleash anywhere that's unfenced would be a smart idea anyway, because big dogs or another type of predator could take off with her really quickly. Which leads me to my next con.
Because she's so small, I worry about her a lot. She's already been attacked by dogs, and nearly died. I'm scared to have her around bigger dogs that I don't know, and really, anything that could happen to a bigger dog and not have a huge affect on them necessarily could instantly kill a smaller dog. So that's something to think about.
Overall I love Chihuahuas, nearly all the ones I've met have been fantastic.
