Most diseases that affect dogs or humans are not transferable between the two species. However, there are some exceptions:
Rabies
Rabies or Hydrophobia (literally,' fear of water' and derived from the fact that infected individuals usually show an aversion (phobia) to water (hydro)), is a disease that can be transmitted to dogs or humans by the bite of many mammals, including dogs, cats, raccoons and foxes.
In the first stage of the disease the infected dog will exhibit change in behavior and fear. In a second stage the animal's behavior becomes more and more aggressive, increasing the chances that they will bite another animal or a person and transmit the disease. In the third and last stage rabies-infected animals suffer deterioration of the brain and nerve tissue leading to loss of coordination and trouble with bodily functions.
