Heartworm is transmitted from infected canine to a healthy one through a mosquito. This means that if there is a pack of coyotes near your home, your pets are at a very high risk of getting infected with this parasite.

There are different types of these diseases, but sarcoptic mange is the one associated with coyotes and their canine relatives. It is a debilitating disease transmitted by a mite that infects the animal by burrowing into their skin. Urban coyotes often serve as hosts to this pathogen and can spread it to pets, and rarely to people. However, the risk of transmission is quite low as it requires direct exposure to the infected coyote. An animal infected by mange typically loses most of its hair, succumbs to exposure, and becomes more vulnerable to other infections.
