Final answer:
Skin diseases from dogs that can infect humans include dermatophytic skin infections like ringworm and hookworm-caused cutaneous larva migrans, leading to itchy rashes and skin tracks.
Step-by-step explanation:
Two skin diseases of dogs that can be transmitted to humans are dermatophytic skin infections and cutaneous larva migrans. Dermatophytic skin infections, such as ringworm, can be transmitted when humans come into contact with fungal spores present on the skin or fur of infected dogs. Ringworm causes a characteristic round, red, and itchy rash to appear on the skin. Cutaneous larva migrans is caused by hookworms, specifically Ancylostoma braziliense, which is found in dogs. When these larvae penetrate human skin, they cause itchy, pruritic tracks to appear.
