Answer: In 2030 or 12 years later
Explanation:
The Chinese Calendar is based on 12 different zodiac animals or signs, some of these include the rat, the dog, and the pig. Additionally, these zodiac signs have a strict order, and every year is associated with a specific zodiac animals and its features. This creates a cycle of 12 years, which means every 12 years the same zodiac animal is repeated. In this context, if 2018 was the Year of the Dog, the next Year of the Dog will be 12 years later or 2030, which applies not only to the Year of the Dog but to any other zodiac animal in this calendar.
