When the dog falls asleep, is it nocturnal emission? No, this is not a sign of ejaculation. It is normal for the anal gland to secrete secretions when the dog sleeps. This secretion usually has a odor and can be mixed with urine or other body secretions. The smell and presence of secretions is normal.
Generally, dogs are sexually mature when they are 8 months old and will have gender characteristics, which may cause sexual manifestations such as "nosperm". If there is no need for reproduction, it is recommended to take the dog to sterilize it, which is the best for the dog's body and avoid some reproductive diseases.
Dogs are usually around 7-8 months old, and large dogs may develop estrus later. The symptoms of estrus are generally reduced appetite, irritability, peeing everywhere, the penis will twitch from time to time and flow out with yellow liquid. Some dogs may keep licking their penis. Of course, there are individual differences, and not every dog will show the same behavior.
