Look inside Mickey's ears. If you see black/brownish/reddish stuff it is an ear infection. If you can't see anything take a q-tip and check a little lower. Dog ears are not like humans you can not bust the ear drum. The ear is shaped like an L. So, don't worry about hurting her. If you see the black/brownish/reddish stuff get Mickey to the vet. He will probably put her on drops and pills.
Katy gets them when the weather changes. My vet said that it is like allergies
Good Luck |
