Hi. My little 2 year old Yorkie named Coco is starting to growl and bite at me every time I try to pet her. It's not like she is a new dog, I've had her for 2 years and she always loved me and I loved her equally. Suddenly, I got home today and she started barking and snapping at me as if I was a complete stranger. I'm guessing that she just doesn't recognize me with my hair up (I have bangs) and no makeup, I just don't know. PLEASE HELP ME! I LOVE MY YORKIE SO MUCH AND I WANT HER TO LOVE ME BACK AGAIN!!
