Which sign is indicative of ear mites in dogs?

The presence of ear mites in dogs is commonly indicated by head shaking and ear scratching. These actions occur because ear mites cause intense itching and irritation in the ear canal, prompting the dog to shake its head in an attempt to relieve discomfort. Additionally, the dog may scratch its ears excessively, which can lead to further inflammation and potential secondary infections. This behavior is a clear sign that the dog is experiencing distress due to external parasites like ear mites.

In contrast, frequent barking, lack of energy, and excessive shedding do not specifically indicate the presence of ear mites. While these symptoms may suggest other health issues or discomfort, they are not directly linked to the presence of ear mites in the same way that head shaking and ear scratching are. This makes the specific signs of head shaking and ear scratching crucial for recognizing ear mites in dogs.
