I have a Chihuahua who was pregnant once before, her and the male did NOT tie.... she had 3 pups exactly 65 days later.. Now here is my question... the male did try to "get her" again, and again no luck for him.. I was relieved... as she had an upcoming appt to get spayed... She was on meds, then went into heat and we had to play the waiting game...Now... This last week or so shes gotten larger in the stomach.., teets are larger shes digging again and sleeping more... I have made an appt. for her to see our Vet on Monday but i have about a thousand questions going through my head... She is showing the same signs as before... but since i did not plan on breeding, I did not even considering writing down the date when he tried to tie... If she is pregnant based on some of my estimated dates, she should be due now... I have not felt any puppy movement unlike the last time.. Could it be that when he tried she just was not ovulating, and the conception didnt take place for a few days or so after? Is it possible that with one puppy , if he/she is tinier, could that be why we may not feel movement yet?? I am hoping that she is not pregnant... I want to get her spayed... She is my baby, not a breeder... and she is my world... If anyone could give me any ideas to help get me through the weekend until she can see the vet i would greatly appreciate it... Does anyone know how long a males sperm can survive? I used to always think that without a tie a female could not get pregnant... and when i took her to our vet when she was pregnant before, he asked me how long the tie was, when i told him there wasnt one,he actually argued with me saying that its impossible... I was in shock... and i was in shock that he didnt realize it could happen, needless to say... New vet...
