It is normal for dogs to not bleed during estrus

It is also normal for some dogs not to bleed during estrus. In many cases, the dog’s “peaches” will be swollen in the early stages of estrus and the roots will be relatively hard. Secretions will appear, and owners need to pay attention to hygiene during the dog's estrus. Care and cleaning during mating are very important. It is easy to be infected with some diseases during estrus, so timely care is also necessary.
