Rabies can make dogs afraid of water, wind, and symptoms of pharyngeal muscle spasms and progressive paralysis. This is a zoonotic disease. Humans have a high mortality rate from rabies, so if a person is bitten by a dog, the bitten person must be vaccinated against rabies. It is worth noting that even if the dog is vaccinated against rabies, the person who is bitten will need to be vaccinated. In addition to rabies, dogs can transmit fungal skin diseases, parasitic diseases, chlamydia, and mycoplasma to humans.
