Do female dogs bleed after mating for the first time?
Female dogs bleed everytime when their heat cycle begin, mating has nothing to do with it.
A responsible owner will have its dogs neutered. If an owner prefers not to do this, the ONLY way to prevent mating is to isolate the female when she is in heat and not allow her to be anywhere near male dogs. Warning: a female in heat will do whatever she can to get loose because the breeding instinct is very strong.
Most dogs menstruate (come in season) approx every 6 months and the first time can be any time from about 7 months of age, they bleed for about 2-3 weeks. During this time they can become pregnant so if you don't want to have your female dog(s) pregnant, you need to keep your female dog(s) away from male dogs for this time.
No, not every mating is successful. There is usually considered to be a high probability of a successful mating if the male and female ''lock'' (where the males penis swells whilst inside the female) for over five minutes. However, even with a successful lock not all matings produce puppies. Most breeders will mate their Dogs twice 48-hours apart to ensure the best chance of pregnancy.
Dogs tend to mate whenever an intact male can find a female in heat. They mate when they want to. When they are brought together for breeding purposes. Female dogs only come into heat 2 times a year. So that means a female dog can only have two litters a yr. The best time to mate two dogs is while the female is in heat A female dog can start mating after the first menstruation/bleeding…
