Archeologists unearthed the mummies of dogs in an ancient tomb just outside of Cario. The 568 feet long and 459 feet wide tomb was discovered by the researchers from Cardiff University in Whales.

The 2,500-year-old Egyptian catacomb in Saqqara, the necropolis of Memphis contains the remains of around eight million puppies and grown dogs.

The scientists believe that the dogs might have been sacrificial offerings to Anubis, the death god of ancient Egypt, a temple for whom stands next to the tomb.

The project's director Paul Nicholson from Cardiff University's School of History, Archaeology and Religion told CNN said that it was not some sort of blood sacrifice, instead a religious act that's done for the best possible motive.

He told the online journal Live Science that animal cults seem to have been a major part of the Egyptian economy at the time.

He said, "Maybe you're hoping that the animal will help someone in your family who has died recently (so that) Anubis will take care of that (relative)".

A sample of the number of mummies in a part of the catacombs was taken by the researchers. They then used that sample to estimate how many mummies existed in the tomb. Researchers also found the remains of jackals, foxes and several falcons. However, nearly 92% of the remains have been identified as dogs.

Nicholson further discovered that the mummified puppies did not have any identifiable injury such as broken necks that depicts a physical action.
