How can I tell if my Labrador Retriever is in heat and ready for breeding?

Answer by  marty17 (56)

Dogs usually come into heat about four times a year. They will have a bloody discharge and often search for a mate. Dogs should be at least two years old before breeding. If they are bred before the age of 2 it can have serious health consequences for both the mother and pups.

The most obvious sign is when your large breed dog starts to bleed during estrous. Additionally, he vulva will be swollen, and she'll be urinating quite frequently, sometimes two to three times as often as she normally does.

Most obvious heat sign - bleeding, I would not breed her till her third heat cycle. Take her to the vet for a swab to determine the estrus cycle stage.

You will see the other doggies run after her when you take her outsides.

You will know trust me she will leave blood spots wherever she lays down and she will lick herself constantly. And any male dog in your area will be at your house.
