Which mange mite tends to spread easily between dogs?

• A. Demodex
• B. Sarcoptic
• C. Both
• D. None

Answer: (B)

Contagious transmission is the key idea here. The mite that causes sarcoptic mange spreads easily between dogs because it passes through direct contact and contact with contaminated bedding or grooming items. In close-contact settings like households or kennels, an infested dog can readily transmit the mites to others, leading to rapid spread and itching in multiple animals. By contrast, Demodex mites are normally residents of the dog's skin and hair follicles; they’re not readily transmitted between dogs, and disease typically shows up mainly when a dog’s immune system is compromised. So, when you’re considering which mange mite is most contagious between dogs, the highly transmissible nature of the sarcoptic mange mite makes it the correct focus.
