[ASOIAF / GoT] Why did dragons shrink in size and get sickly over the course of the reign of the Targaryens to the point where the last dragon died in 153 AC? Is their size dependent upon the environment that they live in?

Its because they had so many that they were always locked up in the dragon pit, they were never properly given the freedom to roam and stand the tests of nature. Many after the DoD were left uncared for by the Targaryens because the King was deathly afraid of them after his mother was executed via dragon food. Same reason why so many animals do way worse in captivity such as Orcas, they have lower life expectancy from being constrained in such a small enviroment and lack of social bonding with others of their kind.
