Ancient Egyptian hieroglyphics depict Anubis, the god of death, as having a dog’s head. Some dogs in ancient Egyptian civilization were buried in the sacred Anubeieon catacombs in Saqqara, Egypt. Ancient dog owners were also said to mourn deeply for their deceased canine friends.

If you look closely, you will see a bit of the haw at the lower inner corner of your dog’s eye.
