Usually between six months and a year old, but it is different for each dog.
No they can not and they will typically not let a male mount them if they are not in heat.
Female dogs go into heat when they think of mating, they get excited, then the male dogs will mate with them... however a male dog can make a female one to go into heat by licking the dog's vulva with their tongues...........
well mine is 8 months and she still hasent..she should anytime soon.
if they are not female and are not fixed
They can be bred when they have their first heat cycle which can be as early as four months but is more typically around six months. It is generally not recommended to breed a dog on it's first heat.
There is no reason to give a female dog medications for a first heat. Having a heat cycle is a normal thing for a female dog. If you are not going to breed her, then have her spayed as soon as she is out of heat. She will live a longer and healthier life. Cut down her risks of mammary tumors, uterine infections, perianal tumors, etc.
No, male dogs do not go into heat. Only female dogs go into heat, which is a period of fertility and reproductive readiness. Male dogs do not experience this physiological process.
I have a female Newfoundland and she just went into heat right at 6 months old.
Female dogs heat usually lasts 3 weeks.
Female dogs typically go into heat, also known as estrus, twice a year. During this time, they are receptive to mating and can become pregnant. If a female dog has been spayed, she will no longer go into heat.
they have periods but then it is called going into heat
No they do not the female dog has to be in heat
