I got a little girl yorkie for xmas. She was good until I took her to the vet to get her shots and heartworm. They shaved her back end. She is almost a year old. They said she was fixing to go in heat. But I have not seen any sign of that. Now she has started peeing every where. Beds, Floors on anything. How can I stop this? Is this normal? I have a male yorkie that I have had for 6 years he is 6. I never went through this with him. This is my first female dog. I need some advise please.
