So my almost 2 year old intact bitch is in heat and she whimpers/cries over EVERYTHING. I don't know how to make her happy and it's making me upset. She cries when I leave the room, when I don't let her run around the yard for hours, she'll lay on the bed and look at me and cry, she'll jump off the bed and stare at me and cry. She's not normally like this, she's always been a reserved, even towards me. Is this normal for a bitch it heat or is she actually in pain and needs to be vetted?
