When it menstruates
Most dogs have their first heat cycle between the ages of six months and a year.
My dogs first heat cycle lasted about 4 weeks.
First of all dogs cant back flip on a motor cycle. Some can do a backflip but dogs on a motor bike its hard to picture it.
its hard to answer like who came in first ... egg or chicken?
The menstrual cycle, or estrous cycle, in dogs typically begins when they reach sexual maturity, which can vary by breed. For most dogs, this occurs between six months to two years of age. Dobermans, Dalmatians, and Chows generally start their first heat cycle around six to twelve months old. During this cycle, which lasts about three weeks, female dogs may exhibit behavioral changes, swelling of the vulva, and possibly bleeding.
The smaller breeds of dogs tend to have their first estrus cycle at an earlier age, while the large and giant breeds of dogs may not come into heat for the first time until they reach eighteen months to two years of age
Female dogs go through a heat cycle, called estrus, every six months. She will have proestrus, or a bleeding cycle, before her true heat cycle during which she is very receptive to the advances of male dogs. This heat cycle lasts for several days up to three or four weeks.
It is the fertile section of their menstrual cycle.

Yes! A therapy should be spayed (preferably) before her first heat cycle, at around 5-6 months of age.
The average age for a first heat cycle is around 6 months of age. Although, larger breeds can have their first heat stage as late as 18 mths.
