The symptoms as you describe them sound more like a dog in heat rather than pregnant. The heat cycle lasts about 3 weeks, with the first week having a bloody discharge....turning clear as they go into the second week (the most fertile time typically), and then a week of them going out of heat. Do not assume she is 'safe' during any of these phases as some can conceive early and some later in the cycle. She should be closely supervised throughout her cycle and not allowed to be around any male. It only takes a few seconds for a tie to occur.
In any case, a vet visit is in order. I agree with the others that breeding Yorkies is not a casual undertaking and you certainly put your girl's life at risk. That is under the best of circumstances. Allowing a girl in heat to roam and be possibly impregnated by who knows what is downright dangerous.
Having your girl spayed promptly would be the only practical advice I could give. Many vets will not spay during a heat due to the increased blood loss, but she could certainly be spayed shortly after.
From your post, it's possible she could have already been with a male, but don't add to the situation by letting her loose at all any more. Keep her safely away from any males and see your vet, tell him/her the situation and discuss having her spayed at the earliest possible time. |
