Mites in Dogs: How to Identify, Prevent, and Act in Time

Dog mites are microscopic parasites that can cause anything from mild discomfort to serious skin problems if not detected and treated in time. Recognizing their symptoms, using appropriate products, and maintaining a good hygiene routine is essential to protect the dog’s health and well-being.

What Are Mites and How Do They Affect Dogs?

Mites are tiny arachnids that can live on a dog’s skin, coat, or ears. Some are part of the natural flora, but when they multiply excessively, they can cause problems such as itching, hair loss, skin infections, and general discomfort. The presence of mites can affect both puppies and adult dogs, and it is more common in immunocompromised animals or those in contact with others already infested.

Most Common Types of Mites in Dogs

Sarcoptes scabiei (sarcoptic mange)

Causes intense itching, hair loss, crusts, and bad odor. It is highly contagious, even to humans. Requires urgent veterinary treatment.

Demodex canis (demodectic mange)

Lives in the hair follicles. Excessive proliferation causes bald patches, red skin, and flaking. Mainly affects puppies and immunocompromised dogs.

Otodectes cynotis (ear mites)

Inhabit the ear canal, causing external otitis, dark discharge, intense scratching, and head shaking.

Cheyletiella (walking dandruff)

Produces visible moving flakes on the back. Highly contagious among animals and can be transmitted to humans.

How to Know if Your Dog Has Mites

  • Constant or localized itching
  • Irregular hair loss
  • Redness, scabs, or skin wounds
  • Presence of visible flakes (dandruff)
  • Frequent ear scratching or head shaking

Pro Tip: Regular brushing with tools like the Artero Romeo fine pin slicker brush helps detect skin issues before they worsen. It's an effective method of prevention in professional dog grooming.

Diagnosis and Treatment of Mites

The diagnosis must be made by a veterinarian through skin scrapings or ear inspections. Treatment varies depending on the type of mite and may include:

  • Acaricidal shampoos: formulas with antiparasitic effects, such as Artero Bye Bye, which also acts against bacteria and fungi.
  • Antiparasitic pipettes or tablets: prescribed by a vet based on the level of infestation.
  • Ear cleaning: with specific wipes like Artero Dips Oídos, gentle and alcohol-free.
  • Antibiotics or anti-inflammatories: for secondary infections or open wounds.

Artero Recommendations for Caring for Infested Skin

How to Prevent Mite Infestations

  • Regular hygiene of the coat with specialized shampoos.
  • Frequent checks of the skin and ears, especially in areas with folds or dense fur.
  • Avoid contact with infested animals or high-risk areas (parks, daycares, kennels).
  • Periodic use of external antiparasitic treatments prescribed by a veterinarian.
  • Cleaning with ear wipes and technical brushing as part of a professional routine.

Tip from the Artero Professional

“In professional dog grooming, we are often the first to detect signs of mites: areas with irregular hair loss, reddened skin, or a bad odor in the ears. That’s why it’s essential to carefully check the coat and always work with clean tools and technical cosmetic products like Bye Bye or Spa Vital.”

The infestation can worsen and lead to severe infections, hair loss, and suffering for the animal.
Do regular bathing products eliminate mites?
