In India, you can legally marry any animal you want but dogs seem to be the most popular choice.
This practice called Human-animal marriage is a marriage between an animal and a human.
Marriage between zoophile humans and non-human animals isn’t acknowledged in law by any country at present, though historically individuals have married anima
ls as part of spiritual traditions or to bring good luck, often involving elaborate ceremonies.
Such marriages as are allowed by tradition, or within a culture, will often be symbolic or ritual, instead of the more normal popularity of a marriage. In the 21st century, there have been numerous reports from around the world of humans marrying their pets and other animals.
The practice of animal-human marriage has made appearances in several mythological stories and folklore and is often understood to mean a deity-human marriage involving gods or heroes.
It is done to ward off bad spirits. One man in New Delhi
explained the process: As a child, he stoned and hanged two dogs, and he was convinced the illnesses he had later in life were punishments for his cruelty.
He visited a local astrologer about it, who told him he had only had one way to remove his curse—he had to marry a dog. The man’s family approved. They even helped him pick out the best dog to be his bride. Then they threw a lavish wedding cere
mony, complete with a feast, to celebrate the eternal union of man and dog.
The tribal custom is also intended to safeguard a child from demons. For instance, the Santhal tribe believes a child is in grave danger if their very first tooth appears on the upper gum. A canine marriage is said to be the only way of warding off evil. Although the child can remarry a human after growing up.
