I am getting more and more worried!  I got Darby two weeks ago.  The shelter worker told me that they "thought" that she was going into heat.  I have never had a female dog before and know next to nothing about them.  Here are her symptoms:   Her vagina and nipples were swollen when I got her.  They appear to be slightly more swollen now.  She has not bled yet at all, but I've heard that some dogs don't.   She is not humping things.  She looks like she has gained weight, but I could be imagining it.  Jerry is very interested in sniffing her, but she doesn't show any sexual interest in him.  (He's neutered, thank goodness.)  Can anyone tell me if these are symptoms of heat or pregnancy?  I got her on Wednesday, May 9th and this is when they told me that they "thought" she was going into heat.  They didn't give me any indication of how long she had been showing symptoms of heat or even how long she had been at the shelter.

Okay, I called the shelter.  I do not have a good feeling about this.  She was brought in as a stray on April 27th.  The girl that I talked to told me that "if" she's pregnant, her supervisor said I can bring in the puppies and they'll get rid of them.  (Whatever that means. )  It sounds to me like now they're trying to cover their a**es.  I asked her if she was showing any symptoms before I adopted her.  She told me that she just noticed she was swollen that day, but hadn't really paid much attention.  I'm guessing we'll be taking x-rays soon. 

This is terrible! If she is pregnant, I think you need to spay her anyway, asap. With out knowing what she mated with, it can be very difficult/dangerous for her. I know no one wants to 'lose' puppies, but you have to think about Darby. Poor baby girl.
