Stupid answer. The oldest dog is in the low twenty's. They can go longer than humans, I had a Dachshund who got pregnant at 14 and had 4 pups.
About 8 months old
The absence of heat signs in your 4-year-old dog could be due to several reasons including underlying health issues, pregnancy, or a delayed heat cycle. It is best to consult with a veterinarian to determine the cause and ensure your dog's well-being.
You don't. If the dog is old enough she'll come into heat on her own (unless she's spayed- then she won't no matter what).
how do I know if my female dog is in heat?
Usually between six months and a year old, but it is different for each dog.

Just like a women..for a long time
Yes, some dogs take longer than others but most come into heat before a year old.
Dr freeze because he has never been in hot heat right
Usually between six months and a year old.
Female dogs can get pregnant as soon as they have their first heat. But, breeding them on their first or even second heat IS NOT recommended. When a female can come into heat depends on the dog and size. Small dogs can come into heat rather quickly while large dogs can take up to a year or more.
