My Sadie is 11 months old. I think she is on her cycle and she is so swollen. Is this normal? Should I take her to the Vet? I hate to be graphic but it looks like shes giving birth to a ping pong ball! It doesn't seem to hurt her and she just keeps licking (again sorry for the graphic descriptions) I am not sure if this is normal. I have talked with other people and they say the swelling is normal but the bubble like thing is freaking me out!
