Dog Age Conversion Models

The video tutorial explains how to calculate a dog's age in human years using a new equation. Traditionally, a dog's age was calculated by multiplying by seven. The new method uses the formula: human age = 16 * ln(dog age) + 31, based on a study of Labrador retrievers. The video compares the old and new models using graphs and examples, showing that the new model reflects rapid aging in early years and slower aging later. It also demonstrates using Desmos for calculations and highlights the need for a calculator with the new model.
