How do I tell if my chihuahua is pregnant?

My almost 2 year old chihuahua came into heat over 2 weeks ago. She finally got stuck to a male chihuahua last Wednesday and then got stuck together about 4 times a day from Wednesday til Sunday. What are the possibilites that she got pregnant? How will I be able to tell? Thank you so much for any help!My chihuahua was free. My mother in law breeds them and gave me her (pick of the liter). We aren't selling our chihuahua puppies. We are giving one of them to one of our friends and if she has another, we will find someone who wants one or keep the other. I don't really expect ours to have but one or maybe 2 because she is so small.We were only breeding her this one time and having her fixed after she has the puppies to lessen the chance for breast cancer (per our vet).

how much did u get the chihuahua for?

the chihuahua will cstart to act unusual. behaviors such as obsessive barking and not eating.(i have3)

The best thing to do is take her to the vet. If she is then she is going to need a vet soon anyway and chihuahuas are very fragile when giving birth to a litter of pups,good luck

Dip it in lemon juice and hold it up to some black light..... apparently

i usely tell when my animals are pregeant by there nipples,they get hard and stay that way.

She may ask you to got to the store for unusual items such as pickles and ice cream.
