How Old Are Female Dogs When They Stop Going Into Heat And No Longer Can Have Puppies? Maybe I Should Have Said She Was 10 1/2 Years Old
No one can answer that question. I have seen dogs go into menopause by skipping a heat and I have seen dogs conceive but because they were older and always had puppies every six months, they had fewer and fewer pups as the years went on. I have also seen a 11 year old dog have pups even though the litter was very small. It all depends on all your dog has been through and her health.
How do you know?
It only stopped after a had her fixed, which was due to a tumor she had.
I'm not a vet, but I would safely say 8 years because I had 3 female dogs who attracted males for that period of time, give or take a year.
