Demodectic Mange in Puppies
Demodectic mange, also called red mange, demodex, or demodicosis, is a skin disease caused by Demodex canis, a cigar-shaped microscopic mite that is a normal inhabitant of canine skin and found on most healthy dogs. The mite infests hair follicles and occasionally the sebaceous glands of the skin. In dogs with healthy immune systems, the body can naturally manage the number of mites on the skin. However, demodectic mange typically occurs when a dog's immune system is suppressed, allowing the mites to present in excess numbers that cause hair loss on the face or the dog's body. This disease is not contagious to other dogs, but instead, it occurs in dogs with genetic defects that weaken the immune system.1 Demodectic mange should be treated as soon as possible to prevent the disease from spreading to more areas of the body. If you suspect that your puppy has demodectic mange, consult your veterinarian to begin diagnosis and treatment as soon as possible.
