7 dog years = 1 of our years
I will assume you are talking about the dog's heat cycle. A female dog does not have a menopause, as people do. Their cycles continue their entire life, though in it's elder years the cycle can become less predictable as to when it occurs. A female dog no matter it's age can become pregnant, but that doesn't mean it's healthy for an older dog! This is why female dogs need to be spayed, preferably before the onset of their first heat cycle.
No! See your vet immediately!
The first heat cycle for a female dog would be between 6-24 months. If she doesn't have her first cycle by then, you take a trip to the vet. And it doesn't necessarily matter what kind of dog it is to have a certain heat cycle. Hope this helps!
A dog's heat cycle is 3 weeks. It does not matter what breed or size of dog it is, they all have the same length for their heat, which is 3 weeks.

It all depends on the dog and sometimes breed, usually every 6 months to one year, they go into a heat cycle. After the birth of puppies, some bitches go into a small cycle and they should NOT be breed during this cycle, it is a natural cleansing process. Ethically, they should only be breed every other cycle or better yet, once every two years if they go every 6 mo.
The three-year cycle is year A, B and C.
The animal that is represented after the year of the tiger is the rabbit. This follows a cycle of twelve animals, each represented in a pattern and each lasting for one year. This cycle will last a total of twelve years. The animals in order are rat, ox, tiger, rabbit, dragon, snake, horse, goat, monkey, rooster, dog, and pig.
As of June 2014 we are in year A of the Sunday cycle, and year II of the weekday lectionary, and will be in them until the First Sunday of Advent, on 30 November 2014 when we will start year B of the Sunday cycle, and year I of the weekday cycle.
No, not at all! Dogs don't develop emotional problems over bodily functions, such as their heat cycle. Your dog will be better off for being spayed.
