What is demodicosis and why should Neo owners worry about it?

Demodicosis is also called demodectic mange. It should not be confused with the much more serious sarcoptic mange – demodectic mange is generally easily treatable.

However, some breeds are more prone to demodicosis than others – and sadly Neopolitan Mastiffs are one of them. The reasons aren’t known, but may indicate a slight weakness in the immune system. Demodectic mange is caused by an excessive number of mites on the dog’s skin – so it could also be that those wonderful wrinkles provide a few more places for them to hide. Either way, demodectic mange causes fur loss, redness and irritation of the skin, scaly skin and lesions. It can also affect a dog’s appetite.

Demodectic mange is formally diagnosed by skin scrapings – the vet may also take a urine sample to eliminate other causes of hair loss and skin irritation. Fortunately, in most cases, localized mange goes away on its own – it may not even need to be treated. It’s most common in puppies between 3 and 6 months of age. To treat the itching, benzoyl peroxide is often applied to the lesions, and the dog should be watched – and kept from scratching those itchy spots to make them worse. If the dog does scratch a lot, they may end up needing antibiotics.

Unfortunately, in some cases, demodicosis becomes generalized and chronic. If this happens, the dog will need oral or topical medication – and they may need to be medicated for the rest of their life. Most vets don’t recommend breeding dogs with chronic demodicosis – it can be hereditary and the mites can be passed to the puppies when they nurse.

In most cases, demodectic mange is an annoying puppy disease – but it’s still one you should watch your Neo for and if in doubt, go to your vet.
