I know she is bound to become a little lazier, but my 11 month old Shih-tzu, the love of my life, is acting strange. She had her first cycle about a month ago and since she won't come downstairs in the morning and never wants to go outside (before I couldn't get her to come inside). I'm wondering if it is just her getting older and "becoming a woman!" Also, I know she can't be pregnant, but her nipples are swollen and I have read it is normal.... is it?!??! Thanks so much for any advice or suggestions!
