Scabies is highly contagious among dogs and cats and can be transmitted to humans so caution is necessary. These mites do best living on your dog, but can exist for several days off a host - up to three weeks in a moist, cool environment. Average lifespan for mites living off a host in a typical home is about two to six days. Areas commonly affected include the chest, tummy, the armpits, and ears - areas where there is not much hair. Scarcoptic mange causes great discomfort to the dogs due to intense itching.
Symptoms of Sarcoptic Mange in Dogs
- Intense itching
- Crusty ear tips
- Hair loss
- Thick and scaly skin
- Crusty, reddish brown lesions due to the burrowing of the mites
- Secondary bacterial infections of the lesions
Demodectic mange most usually affects puppies and young adults (less than 2 years of age) with immature immune systems and older dogs with weakened immune systems.
The Demodex mite spends its entire life on the host (the dog) and cannot live off the dog's body. As such, transmission of this mite is by direct contact only and is not considered to be contagious. The area first affected is usually around the eyes, but may spread to the head and other parts of the body.
Symptoms of Demodectic Mange in Dogs Demodectic mange may affect one or two areas of the dog's body (localized infection) or it may affect the whole body (generalized infection). Most dogs suffer from localized infections.
The one typical symptom of this type of canine mange is hair loss. Dogs with localized infection may have hair loss on the head, around the eyelids, mouth corners, and sometimes on the legs and feet. In more serious cases of generalized infection, there may be hair loss over the entire body. The skin may turn red and become crusty or scaly.
In case of secondary infection, the skin will become inflamed and may ooze. The skin will also give off a strong offensive odor. If you think your dog has either of these conditions, please take them to your veterinarian for treatment.
