How to tell if a dog has mites?

Mites in dogs often leave subtle clues before things get worse—start by watching for sudden, excessive scratching, especially around the ears, paws, or belly. You might notice your dog rubbing their face on the carpet or chewing at their legs more than usual; these aren’t just “normal” dog habits—they’re signs something’s irritating their skin. Sometimes, small red bumps or scaly patches pop up too, especially in areas with less fur.

A close visual check can reveal more details, but you’ll need good light and a gentle touch. Part your dog’s fur slowly, looking for tiny white or brown specks (they might look like flea dirt, but they stick closer to the skin). For ear mites—super common in puppies—peek inside their ears: if you see dark, crumbly debris that looks like coffee grounds, that’s a red flag. Never dig too deep, though—you could hurt their ear canal.

Behavior changes matter too. A dog with mites might seem more restless at night, since mites tend to be more active then, or they might avoid being petted in sore spots. If your normally cuddly pup pulls away when you touch their neck or paws, it’s worth a closer look. Mites can make even the calmest dog irritable, so don’t brush off small shifts in their mood.

When you suspect mites, act fast—but always follow local rules about pet health. Many areas require that you take your dog to a licensed vet for a confirmed diagnosis, not just treat them with over-the-counter products. Using unapproved meds can make the problem worse, and in some places, it’s even against the law. Your vet can test a skin sample and give you safe, effective treatment options.

Preventing mites goes hand in hand with spotting them early. Regularly wash your dog’s bed, toys, and collar in hot water—this kills any mites that might be hiding there. If you take your dog to doggy daycares or groomers, make sure they follow strict cleaning protocols (most reputable spots do, but it’s okay to ask). Mites spread easily, so keeping your dog’s space clean helps protect both them and other pets.

Catching mites early means your dog will be back to their happy self in no time. With a little observation, a vet visit, and following local pet health rules, you can keep mites from turning into a bigger issue. Remember, your dog can’t tell you when their skin hurts—so staying alert to those small, telltale signs is one of the best ways to keep them healthy and comfortable.
