A female dog (of any breed) first goes into heat sometime around the 6th,7th, or 8th month of age. There's no way to predict when. For this reason, it's best to have a female dog spayed before her 6th month of age.
Female dogs get significant health benefits when they're spayed before the onset of their first heat cycle.
Has she come on heat yet?
A few weeks.
A spayed female will not come into heat, but may choose to accept males through force of habit if she has bred before. She will still have the standard "female cat" scent, though only cats can detect it.
The best time to mate a standard poodle is when he or she is sexually mature and reached his or her full height. This usually takes 12-24 months. Also have any necessary tests performed for your poodles hips, eyesight and any other necessary tests that your Vet recommends. This way, if your poodle breeds successfully, it is unlikely the litter will inherit any genetic problems from your dog.
Every 6 months.
you have to wait for them to come into heat If the female is in heat she will eventually come around.
Normally a female (of any breed) will come into heat approximately every 6 months. It could be sooner if they are around another female in heat.
You can't. They usually come into heat every six months, providing they are healthy.
You don't. If the dog is old enough she'll come into heat on her own (unless she's spayed- then she won't no matter what).
If a male dog licks a female dog it will not bring her into heat if she is not at the right stage of the estrous cycle. Hormones such as estrogen must be at the right level for the dog to come into heat. The short anser to your question then is, "no".
No. Many dogs that go in to heat earlier are the ones that are bigger and can mature faster. The bigger breeds, such as a great dane or so, would go into heat much faster then a chihuahua for example. This si because the great dane can mature faster then the chihuahua.
Generally it is around 6 months old. Some dogs don't go into heat until they are passed a year old. Never breed your dog on a first heat. Research before breeding. Find a mentor, but don't just breed her. She will be in heat for at least 21 days. Continue keeping her away from other dogs though until you are absolutely sure she is no longer in heat. I have a dog that stays in heat 5 weeks minimum! She's always been that way.
