My Bigger dogs come in heat about every six months. My Yorkie has only had one heat so far and that was when she was six months, She should be coming in again soon . I have always heard if your female comes in heat at age 6-7 months then they will normaly come in again an another 6 months but if they come in heat at eight months then their more likely to just come in heat once a year. im not sure how true this is Like I said this is what I have heard. My dogs have alwasy came in heat every six months. |
