No, hyenas are not related to dogs. Despite some superficial similarities in appearance, hyenas belong to a different biological family and are more closely related to cats than dogs. Hyenas belong to the family Hyaenidae, and there are four extant species: the spotted hyena, the brown hyena, the striped hyena, and the aardwolf. Hyenas have unique features that set them apart from both dogs and cats. They have powerful jaws, a large head, and strong teeth designed for crushing bones. Additionally, hyenas have a unique social structure and communication system, which is different from both dogs and cats.
