Im brand new to this site! So I'm not really sure how exactly everything works! So please bare with me! I have a question and I'm hoping someone can please help me with a answer!! OK I have a 10 month old English Bulldog and she's about 2 weeks out of her first heat. I'm very curious to know if her teats are suppose to change massively?? I'm scared that a friend's dog tried mating with her while I let her out to potty!! I asked friend to NOT bring his dog over but he definitely didn't listen! Can someone please help me with my questions and concerns please!!?
