No, dog ear infections are not contagious to humans or other animals. However, certain types of ear infections in dogs can be caused by ear mites, which are highly contagious between dogs.

Ear infections in dogs are usually caused by bacteria, yeast, or a combination of both. These infections can occur in one or both ears and can cause symptoms such as itching, redness, discharge, odor, and discomfort. Although ear infections are common in dogs, they are not contagious to humans or other animals.
However, as we mentioned earlier, ear mites can cause ear infections in dogs, and these parasites are highly contagious between dogs. Ear mites are tiny parasites that live inside the ear canal and feed on the wax and oils in a dog’s ear. They can cause intense itching, redness, and inflammation, and can also lead to secondary infections.
If your dog has an ear infection, it’s important to take them to the vet for a proper diagnosis and treatment. Depending on the cause of the infection, your vet may prescribe medication, ear drops, or other treatments to help clear up the infection and relieve your dog’s symptoms. In addition, if your dog has been diagnosed with ear mites, it’s important to treat all pets in the household to prevent the mites from spreading.
