Dogs can be infected as well but, since dogs more commonly get ear infections of other types, ear infections in dogs rarely involve mites. Ear mites readily transmit from host to host by physical contact. Ear mites came from some other animal with whom your pet has been socializing. Because mites are easily transmissible by physical contact, treatment for mites often must include all household pets. The presence of the mites is very inflammatory and can generate very irritating ear infections.
Skin disease can also result from infection by the ear mite.
Ear mite infection is certainly contagious among cats and dogs. Typically, the victim is an outdoor cat. There are numerous products available for ear mite eradication. Because of this limitation, such products must be used for at least the duration of the 21 day life cycle of the mite. Some specialists recommend a 30 day treatment course with such products.
