Which is the most frequent acarus that can affect my dog?

It depends partly of the region where you live, the below mentioned mites are all very frequent in dogs. Skin irritation caused by any of these mites is called mange, and can be hard to eliminate. The Demodex canis mite is located in the deeper part of the hair's follicles, and is normally associated to breeds with short hair, specially theDachshund.It can cause the loss of hair, and make the skin thicker, which will allow access of bacteria into the damaged tissue, causing the appearance of pustules, which will aggravate the dog's situation. The Demodex expands from a female dog to her puppies, though symptoms may not appear immediately. To confirm the presence of Demodex, a microscope is useful to watch the skin scrapings. Normally, this infection is hard to treat, and mating of the female should not be allowed to avoid transmission to her puppies. The Sarcoptes scabiei establishes in the skin, and the first indications of its presence are some red spots that can be noticed on the internal surface of the thighs. The complete vital cycle takes place in the dog, producing great irritation. It is treated in the same way as Demodex. If you suspect the presence of mites, take precautions to prevent them expanding to people in the house, specially kids. Another skin mite, that usually affects puppies, is the Cheyletiella yasguri. In case of older dogs, this means an excessive development of dandruff in the hair, this is part of the same mite when they are white in color. The ear mite, known as Otodectes cynotis, lives in the ears. These mites cause irritation when invading the sensible tissue, and contribute to produce infection. You can see them in site through an auroscope, but an accumulation of red grayish brown wax in the auditory channel is an indication of its presence, specially if the dog repeatedly scratches his own ears. Ask the veterinarian about treatment to follow. Normally, most of mites live in the dog's body as long as their vital cycles last. The exception to the rule is the Trombicula autumnalis mite. In this particular case, they are parasites only during the larval state of the vital cycle. Adults, small and thin, are free red forms, while larva is found in vegetation, and generally attack the paws of the dog, causing serious irritation and causing the dog to bite his own legs. A careful examination will discover the responsible minuscule groups of larvae. North America's nigua (Eutrombicula alfreddugesi) produces similar symptoms, and to kill the larvae you should wash your dog's legs and paws.
