However, giant breeds could take up to two years or even more than that before those breeds of dogs could come into their heat session for the very first time in their life. Many dogs face their first heat in silence and they do not have any kind of clinical signs that might be associated with the estrus.

But, the main question is how will you know that when is the best time for mating your dog. Well, that can be pretty difficult to judge or even guess because you are not an expert here. Most dogs tend to ovulate and those dogs are receptive around their 11th day of estrus.

The discharge that happens to the female dogs usually contains few amounts of blood and during that time the female dog would be actively looking for a male partner. During this time the female dog will stand in her position and present her hind end position for the male/partner dog to be mounted. Or the female dog might end her tail to her side which is also an indicator that she is ready for mating.

However, there are two tests that can be conducted on dogs to check when they can mate their dogs. The two tests are vaginal cytology or vaginal smears and serum progesterone test. These are two simple tests that can be conducted to determine when a dog can mate.
