Dog in Heat - How can you tell? My Yorkie, Misty, will be 3 years old in November. She got pregnant once when she was only 16 months old and had only one pup. Now I have some folks who are wanting to know when Misty will have a litter. I don't have a problem with that since they want a pup from someone they know. My question, how can I tell when she's in heat? I have never seen any blood nor have I seen her act any differently. |
