My dog has had an ear infection for months. At least we think it is an ear infection. You can tell that when she scratches her ears, which is often, she's in pain. And last night she just kept scratching and scratching and so I took a qtip to try and clean her ear. I have done it many times before butafter this time she tilted her head for a few seconds and kept shaking her ears for probably 10 minutes. Ever since last night, I have been so worried about her. Earlier today she was fine, but now she seems a little sad and real tired. I have tried treating her esrs with a cleanser, but she puts up quite a fight when I try. So I gave up doing that. She has had this for months and months. What should I do? I am worried sick for her. She is a 1 1/2 year old chihuahua. She has had all her shots, but not heartworm treatment. What do you think she has? Could it be ear mites? And the stuff that comes out of her ear looks like dried blood. I am so scared she will die. Please send answers!!
