How Do I Know if My Dog Has Mites?

3 min read

As pet owners, we know our dogs can get fleas or ticks—but mites are another tiny pest that can cause big problems. Mites are microscopic parasites that burrow into your dog’s skin, hair follicles, or ears, leading to itching, discomfort, and even serious skin infections if left untreated.

In this post, we’ll break down the types of mites that affect dogs, the most common signs to watch for, and when to see a veterinarian to keep your pup healthy and comfortable.

Why Mites Are a Problem for Dogs

While mites are invisible to the naked eye, the irritation they cause is hard to miss. These pests can trigger intense itching, hair loss, skin redness, scabs, and even secondary bacterial or yeast infections. In some cases—like with sarcoptic mange—mites are contagious to other pets (and even humans).

There are several types of mites that can affect dogs:

• Sarcoptes scabiei – causes sarcoptic mange (“scabies”), highly contagious

• Demodex canis – causes demodectic mange, typically not contagious

• Otodectes cynotis – ear mites, more common in cats but can affect dogs

• Cheyletiella – “walking dandruff,” visible as moving flakes on the coat

Signs Your Dog Might Have Mites

If your dog has mites, you may notice:

• Intense scratching, chewing, or rubbing against surfaces

• Red, inflamed, or crusty skin

• Hair loss in patches or generalized thinning

• Scabs, sores, or thickened skin

• Flaky dandruff-like debris

• Head shaking or ear scratching (possible ear mites)

🔍 Tip: Mite symptoms can mimic allergies, fungal infections, or other skin conditions, so a vet diagnosis is key.

How to Confirm if Your Dog Has Mites

Mites can’t usually be seen without a microscope. Your veterinarian may perform:

1. Skin Scrapings – collecting a small skin sample to examine under a microscope

2. Ear Swabs – to check for ear mites

3. Fur Brushing or Tape Tests – to detect surface mites

4. Blood Tests – in rare cases, to check for mite-related infections

When to See the Vet

You should book a vet appointment if your dog:

• Has persistent itching or scratching

• Develops bald patches or skin lesions

• Shows sudden skin changes that don’t improve

• Has other pets in the household (to prevent spread)

📣 Note: Never try over-the-counter mite treatments without a diagnosis—different mites require different medications, and incorrect use can worsen symptoms.

Treatment and Prevention

• Prescription Medications – topical, oral, or injectable treatments to kill mites

• Medicated Shampoos – to soothe skin and remove crusts or debris

• Environmental Cleaning – wash bedding, vacuum carpets, and clean pet areas to prevent reinfestation

• Routine Checkups – early detection keeps infestations under control

💡 Many modern flea and tick preventatives also protect against certain mites—ask your vet which option works best for your dog’s lifestyle.

Advantages of Acting Quickly

🐾 Faster Relief – Your dog feels better sooner

🐾 Prevents Spread – Protects other pets (and possibly people)
