Hi Kathy and Bella! Mounting/humping is a common behavior with toys , other dogs and even people to establish dominance and is not uncommon especially with the onset of maturity when they feel the need to establish their dominance more effectively- but I was wondering the same thing about my girl! She has always had her favorite sheep but she has been mounting everything lately!' She is just nine months. Same here, no bleeding or swelling but she has just been a little extra 'crazy' this week and went we went to the park she was really sniffy and peed and pooed outside for the FiRST time in her life one after the other. She is a potty pad girl. Any of these other things for your girl happening? I'm so glad you brought this up, I will be watching for these seasoned veterans replies and cross referencing my dorky yorkie library
good luck and thanks for the thread!
