Is it the Lesser Heat or the Greater Heat that starts the dog days?

Neither Lesser Heat nor Greater Heat begins the day when the dog days begin. As the saying goes, "The heat is in the dog days." In my country, the dog days of summer usually occur after the third Geng day after the summer solstice, which is the so-called "the first dog days after the third Geng day after the summer solstice".
There are only 15 days between Lesser Heat and Summer Solstice, while the Dog Days usually occur 20 days after Summer Solstice. Therefore, the Dog Days have not yet arrived during Lesser Heat, but will begin about 5 days after Lesser Heat.
There are three hot days in a row, each of which lasts for ten days, and this is calculated according to the ten number of the heavenly stems. Therefore, the three dog days are divided into: the third Geng day after the summer solstice is the beginning day of the first dog day.
The date of the beginning of the dog days can be simply expressed by the four-character formula "Summer Solstice Three Gengs", that is, starting from the third "Geng" day after the summer solstice, the first dog days is 10 days, the middle dog days is 10 days or 20 days, and the last dog days is 10 days. The "ganzhi calendar" was popular in ancient my country. The days were recorded in a cycle using 60 different names formed by matching 10 heavenly stems with 12 earthly branches. Any day containing the character Geng is called Geng Day.
2019 Summer Solstice Date: June 21, 2019
The first Geng Day after the summer solstice in 2019 is June 22, 2019 (Geng Yin Day)
The second Geng day after the summer solstice in 2019: July 2, 2019 (Gengzi Day)
The third Geng day after the summer solstice in 2019: July 12, 2019 (Gengxu Day)
The first day of the "fu" season this year is July 12, 2019 (Gengxu Day) . Because the first dog days lasts for 10 days, this year's first dog days is from July 12th to July 21st.

What is the meaning of the Lesser Heat solar term?

The time of Minor Heat is between July 7 and 8 every year. The "Collection of Explanations of the 72 Seasonal Changes in the Lunar Calendar" states: "The sixth month is the heat, which is divided into small and large heats. The beginning of the month is small, and the middle of the month is large. Now the heat is still small."
"Shu" means hot. The ancients believed that the period of Lesser Heat was not the hottest time of the year, so it was called Lesser Heat. There is also a folk song about the solar terms that says, "Less Heat isn't that hot, but Greater Heat is the hottest time of the year." It indicates that the hottest period of the year has arrived, but it has not yet reached an extremely hot level.
In ancient my country, the Lesser Heat was divided into three phases: "The first phase is the arrival of warm winds; the second phase is the crickets returning to their homes; the third phase is the eagles starting to prey."
The first sign is the arrival of warm winds: after the Lesser Heat day, there will no longer be a trace of cool breeze on the earth, but all winds will carry heat waves.
The second phase is that crickets live outdoors: Crickets live outdoors means that five days later, due to the hot weather, the crickets leave the fields and go to the corners of the courtyard walls to avoid the heat.
The third sign is the eagle's beginning of prey: The eagle's beginning of prey means that after five days, the eagle will move around in the cool high sky because the temperature on the ground is too high. As the saying goes, "A good fate is not as good as good luck." A person's destiny is already determined, and the only thing that can be controlled is his or her "luck."
