Why is My Dog Scratching at His Ears?
Occasional light scratching is normal. However, persistent scratching or pawing at the ears or head can be an indication of ear infection, injury, excess earwax, something lodged in the ear or skin problems. Some ear problems may not be easily visible and require a deep ear exam by a veterinarian to be properly evaluated. Any discharge, odor, redness, pain, swelling, or masses may indicate an infection or other abnormality. If you suspect your dog has an ear problem, visit your veterinarian immediately. Prompt treatment offers a better prognosis, reduces the potential for chronic disease, hearing loss, and offers relief from discomfort.
My dog has been licking, scratching and biting himself after coming back in from the yard. Is it possible he's having an allergic reaction?
Allergies are one possibility, but it may also be a case of fleas, ticks or other insect bites, an ear infection, or even a reaction to lawn chemicals. It's best to have your vet examine your dog as soon as possible to determine the cause of the behavior and recommend treatment.
