She will start to swell.

Never. But seriously: When the female cat is 'on heat'.
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.
No. However male dogs can still show interest in them even if they are spayed.
Well, if your male is in heat, you either need to a": double check it's business, or b: call guiness book of world records, because only females go into 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...........
if they are not female and are not fixed
I have a female Newfoundland and she just went into heat right at 6 months old.
Female dogs heat usually lasts 3 weeks.
