I have a chocolate lab that is 1 1/2 years old. She is nearing the end of her first heat cycle. She is actually in her 3rd week. She runs free on 5 acres but I noticed her bleeding and her genitalia budding and immediately kenneled her. She couldn't have been more than a day or two into her heat cycle because I check her almost daily because she is our first female dog and I didn't want any unplanned puppy suprises. I noticed today that her teats or nipples are large and more pronounced. Her genitial area is still quite swollen as well.
I have read everything I can about heat cylces and can not find any information on nipples other than dealing with pregnancy.
Is it normal for the nipples or teats of dogs to become enlarged during a heat cycle or am I more than likely going to be having puppy suprises soon?
Would her teats already be swelling if she were pregnant? She is still in her cycle so she would only be pregnant about 2 weeks because she is in the third week of her heat cycle.
Thanks for any info!
