If you think your dog may have mange, it’s important to consult with your vet as soon as possible about mange in dogs. Getting ahead of this disease is vital and your vet will be able to provide solutions based on several key factors and the severity of the case.
It’s important to remain in touch with your dog’s appearance and behavior. Inspect them often and keep note of unusual behavior they might show. In doing so, you can notice any symptoms as they appear and get to the vet sooner than later. And your conversation with your veterinarian will be far more productive when diagnosing and treating the illness.
The key is to be proactive in your pet’s health so that disease can be caught early, and treatment can become more effective because of that. Let’s dive a little deeper into some background around mange, the cause of this illness, symptoms, diagnostics, and treatment.
Knowledge Around Mange in Dogs
There are two main types of mange in dogs: sarcoptic mange and demodectic mange.
Demodectic mange in dogs is most often seen in puppies and immunosuppressed animals. This form of mange is not contagious to other pets or to people but will cause skin issues for the infected pet if left untreated.
We’ll be focusing on sarcoptic mange (commonly referred to as scabies) since this is the contagious type of mange. It’s also more common across pets of all ages and health status.
What Causes Scabies?
Scabies (or sarcoptic mange) is one of the
most uncomfortable skin diseases that a dog can contract. This highly contagious condition is caused by extremely small mites that can cause severe itching and skin irritation and will significantly decrease a dog’s quality of life.
The female mites dig into the top layers of the dog’s skin to lay their eggs. Once the eggs hatch, the larvae dig deeper into the skin to mature into adults. With a 21-day life cycle, the mites can replicate quickly, causing more skin irritation over larger areas.
Is Scabies Contagious?
Canine scabies is highly contagious. It is transmitted through direct contact with a carrier animal, or when a mite falls off the skin of a carrier and survives long enough for it to infest a new host animal. At room temperature, mites can survive for two to six days without a host.
Can Humans Get Mange?
Dogs, coyotes, and foxes are most at risk of infestation from scabies mites. Humans, cats, and other mammals can also be infected, but the mites struggle to survive on our skin for long periods of time.
How to Answer, “What Does a Dog Look Like with Mange?”
What does canine mange look like? Severe, constant itching at any time of year is a classic symptom of sarcoptic mange. Areas with less hair, such as the earflaps, elbows, hocks, ventral abdomen, chest, and legs, are affected most. The mites cause hair loss, a reddened rash, and yellowish crusts to form on the skin in affected areas. Typically, the ear margins and elbows are affected most severely. The ear margins tend to have thickened, crusty material on the tips and yellow scales. The animal may develop a secondary skin infection and severe scratches from the trauma of constantly scratching. The lymph nodes also may swell because of mite-related inflammation. In dogs, the areas most affected by scabies are those with less hair, such as the earflaps, elbows, legs, stomach, and chest. Common symptoms include:
Hair loss
Yellowish crusts formed on the skin
Thickened, crusty material and yellow scales on ear tips
Severe scratches (from constant scratching)
Swollen lymph nodes
Humans who have acquired mites will develop itchy red bumps on their body. These lesions last for approximately two weeks before disappearing on their own, but repeated contact with the affected animal can cause symptoms to last much longer.
What Diagnosing Scabies Looks Like
In comparison to
other skin parasites like fleas, scabies mites are microscopic and impossible to see with the naked eye. A definitive diagnosis is often difficult because mites are not often found on skin scrapings. And so, treatment is frequently based on the suspicion of scabies, rather than a definitive diagnosis.
A visit to your vet is essential if you think your dog has mange. Skin scrapes are typically taken to be examined under a microscope and other tests may be performed to aid diagnosis. Generally, if scabies is suspected, treatment should begin immediately. A prompt response to therapy, like decreased itching, strongly suggests the assumption of sarcoptic mange in dogs was correct.
Can Mange in Dogs Be Cured?
Topical and oral medications are available and very effective. A veterinarian should be consulted about the proper course of treatment. The prognosis for sarcoptic mange is excellent with proper treatment. The most common method of treatment for mange follows these steps:
Clipping the hair from the affected area.
An anti-seborrheic shampoo is applied to breakdown and remove crusts, skin oil, and debris.
An oral medication containing isoxazoline, like Simparica®, Simparica TRIO ® or a topical antiparasitic such as Revolution®, is given monthly. These should be used past treatment to prevent future infestations.
The entire environment, including all objects that have been in contact with the affected dog, should be washed thoroughly and disinfected.
All dogs that have been in contact with an affected animal need to be treated as well. A veterinarian should be consulted about the most appropriate treatment plan. Humans with suspicious lesions should consult their physician for evaluation and treatment. Our shared hope is to see your pet thrive — every day of their life.
