Sarcoptic and Demodectic Mange

Demodectic Mange and Sarcoptic Mange are parasitic skin conditions caused by mites.


Demodectic Mange

Demodex Canis can live on most adult dogs and do not tend to cause any irritation. They live in or near to the hair follicles.  Spending it’s life on the host (dog), pregnant females lay eggs which hatch and mature from larvae and then develop until they reach adult stages. The mite lifecycle is understood to be around 17 – 35 days.

As mentioned, most dogs’ can cope with this mite and are not affected by its presence however this is not always the case. Those at higher risk are:

  • Older dogs’ with a weakened immune system
  • Younger dogs/ puppies, usually under 18 months of age.
  • Dogs or puppies suffering with additional conditions such as skin conditions or illness.


  • Dry, itchy skin (unexplained) & wrinkly skin
  • Hair Loss (can be a small area or larger areas)
  • Red, flaky skin or a rash (can also be dark and hardened skin)
  • Greasy coats
  • Spots (can be filled with pus)

Sarcoptic Mange (Sacoptes Scabiei)

Sarcoptic mange is a skin condition that is caused by the Sacoptes Mite. These mites burrow in to the skin causing intense itching and reddening of the skin, this can be quite painful for your dog. Left untreated, this can lead to skin infections and can make dogs quite poorly.

Sarcoptic mange can be very infections and often contracted by interaction with infected dogs or foxes.


  • Skin irritation, this may start on ears and legs (this can be intense itching)
  • Sore, red skin. This may also be flaky
  • Hair loss
  • Lethargy (lacking in energy)
