My dog's nipples are enlarged and dark after heat. What does it mean?

Pet's info: Dog | German Shepherd | Female | unspayed | 70 lbs

Ok so my dog is now over a year old and she went into heat about a month ago, recently I have noticed that her nipples look enlarged and are kinda a dark pink/red color. Our Male may have gotten her while we were not home. Now he seems to want nothing to do with her as before he was trying to mount her before she was even in heat. What could this mean?

It is quite possible she could be pregnant, or may be suffering a false pregnancy. An ultrasound exam by your vet is recommended to see what is going on so you can start and prepare for puppies if they are on the way - you will need to arrange to segregate the male from the nursing mother if you are going ahead with the pups
