Various cultures and religions attribute holy or revered significance to dogs. For instance, in ancient Egypt, dogs were associated with Anubis, the god of the afterlife and mummification. In some Hindu traditions, dogs are linked to the deity Bhairava and are considered sacred. Additionally, some cultures, like certain Native American tribes, have legends or stories that depict dogs as spiritual guides or guardians. While dogs hold special places in different cultural and religious contexts, there isn't one specific universally recognized "holy" dog across all histories.
