Pet's info: Dog | Chihuahua | Female | unspayed | 1 year old | 8 lbs
I have a female chihuahua that has already had a litter of successful puppies. Her pups are 12 wks and 2 days old. My question is when should she be in heat? I am not wanting to breed her again until her 3rd heat cycle, possibly. I was told between 5 and 6 wks old for the pups. My male dog has tried to mate with her on and off since then and still today!
