I am feel really guilty about getting a new dog. I mean REALLY guilty.

My boyfriend and I have a dog together. it's really his dog, but we are together everyday, and the dog goes everywhere, and so it's basically our dog. He's a chihuahua mix, and the sweetest guy. We rescued him from a woman's house who didnt care about him, and had 10 kids running around and scaring him constantly. I've worked on him a lot and he is more socialized now, but still had typical chihuahua traits.

The other part of the back story. I have worked at a vet since I was 15 now. My first summer there, a woman brought in Chinese Cresteds and I fell in love. I have wanted one ever since.

Well I just got one two days ago. He just turned a year old, he was supposed to be a show dog but it didnt work. he is a "hairy" hairless. He is super sweet, but he doesn't play. He only plays with my cat, or my boyfriend's dog. I know I can get him to play, but I am not sure how? if I try to play with him, he gets scared. And he doesnt understand what chew bones, balls, rope toys, sqeaky toys.. nothing are. he just gives me a funny face. so in the morning or when I get home from work, he is all hyper and happy, and I dont know what to do! All I can do it pet him. It's wierd. He also doesn't make any noise at all.

So anyways, I brought him home two days ago. The second my boyfriend got here with his dog, I wanted to cry. I feel like I am replacing my boyfriend's dog. I feel horrible. I have been crying all these days. I have a week where I can take him back and have my money back. But the thought of taking him back makes me want to cry too. I realize it's only been a few days, but the guilt isnt getting any better. I just feel so torn. My boyfriend's dog doesnt seem that mad so far, but I love how needy he is of me.
I am starting to think maybe I got a mistake getting my own dog at all. I am also starting to think, as much as I love Chinese Cresteds, maybe I should have just found a Chihuahua, because I love all the expressions, the vocals, the needy part of the behavior. =/

I just don't know what to do. I dont want to keep a dog that I will feel I always treat second best when my other dog is around.
This happened before when my parents divorced, we had a dog at my mom's, and the dog from my childhood lived with my dad. Whenever that dog came to stay with us for a weekend if my dad had to go somewhere, I almost ignored my other dog.

I just don't know what to do!
I forgot to add, the Crested is the sweetest dog. He is playful with other dogs and himself some. And he is super sweet. He's a great dog, I do like him.
I paritally feel like I am so guilty I am putting up a wall between me and him.

I've been fostering for rescue dogs for over 16 years. I've always been able to make things work out till they've been placed.

I pulled a foster Chihuahua mix into my home 10 days ago (spayed) She is mellow and unlike any Chi I've ever experienced. No shivers, no aggression, nothing.

She and my neutered male and spayed female seem to have coexisted well -- until yesterday, when (seriously) out the blue she and my female just got into it. The foster dog was the clear aggressor, my female was defending herself.

Now my female is hiding, not coming out, etc. And the Chihuahua is actually seeking her out. She looked for my female afterwards last night, found her in her (open) crate and went at it again. Also again before bed.

Today we've been doing the crate and rotate thing all day. I've called the rescue and they will pick her up, but I can't help thinking that maybe there's a solution I'm not thinking of? I don't want my dog to be uncomfortable.

Any insight?
Yes, my dog fought back but she's really not into fighting which is why she's avoiding confrontation and hanging low (this is not like her at all, she's normally very sociable) The second two times when the foster dog went after her, I was able to pull one or the other away quickly enough to avert an altercation.

I agree, I've already let the rescue know to change her profile to "only dog." I'd hate to see her get placed and a few weeks later be returned for the same reason.

I love dogs-always have..was raised with them, etc. Anyways last year my husband said I could recuse a dog- I saved a Jack Russel from being euthanized. 9 months later he ran away and we never found him. So I rescued a chihuahua mix a few months later. He was the perfect dog! Until he bit one my neighbor's children. It broke my heart but I had to release him to Animal control. Why am I having bad luck with dogs? I just want to provide a loving home for a pooch and I would spoil it rotten. Am I rescuing the wrong breeds? Thanks.
I will add that I have children and the jack russel jumped our fence which is why he took off.
I had no choice but to release him to animal control..he broke the skin and the parents were involved. It broke my heart and he never did that before.
The entire family was in the backyard with the Pip when he jumped and we chased him for blocks. The chi (Rusty) was in the house with me and my daughter brought in her friend and he just went after her (I had him for 6 months and he never did that and in fact I had him professionally trained 1 on 1).
I never left my dogs unsupervised..ask my neighbors they were like my children. They even went on car rides with me. Pip had never tried to jump the fence before..he just happened to do that one time and that was it..he was gone even though we were all outside. Rusty was more of a terrier/chihuahua so he was never snippy before. I don't feel irresponsible towards the care of these animals.

My former roommate moved back to Alaska, and left her dog with me, promising to send for it. It's been a month, and she finally emailed me to let me know that she couldn't send for it, and to find it a new home. "It" is a small Chihuahua mix, about 4 pounds, female, unspayed, no shots or any kind of medical care. I need to find her a new home. Is anyone here into Chihuahua rescue, or would be interested in giving her a new home? Would it be mean of me just to surrender her to the shelter? Being that she is a small dog, I'm nearly positive she will find a good home. My "friend" has never given me a single dime to pay for this dog's care, and the dog is getting a bit expensive. I've tried the local small dog rescue, but they weren't able to take her. What do you all think I should do? The main issue is that I have to rehome her by the end of the month, because I'm moving, and there is no place in the new house to put her.
Thanks for your imput!
We live in Tuscaloosa, Alabama and if anyone is interested in adopting her, I'd be glad to drive a few hours for them to meet her.

So our dog Kisses just had 6 puppies, she a Chihuahua mix of some kind. The father Perdo is all Chihuahua. As far as I know there are 4 males and 2 females. All of them are white, tan, or a mix of both. Any suggestions?
I'm not with the puppies, I haven't seen them yet. I'm going for a visit in February and I promised my dad some names.
