My puppy 8 months just got out of being in heat and now her nipples are hard and swollen 😰 is this normal? I tried looking it up online couldn’t find to much about it , she is getting spayed at one year, it what we have been recommended to do because she is a large breed we were told that it’s best for her joints to wait... I am for spaying and neutering animals. She is not being bred nor did she go to the dog park or get to really leave the house during her heat cycle.
