It is possible he is developing or has an ear infection. These can be bacterial or fungal (yeast) resulting in the symptoms you are reporting. If possible, place an e-collar (cone) on him to prevent further scratching. Have Dooney examined by your veterinarian. A swab of the ear can be examined to diagnose infection. If necessary, the vet can dispense the appropriate medication. Treatment usually takes about 7-14 days to resolve the infection.

    It's probably an ear infection, often it cannot be seen from the outside. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take her to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

    It sounds like Bella may have an ear infection. Ear infections in dogs can be caused by yeast, bacteria, and ear mites. There is nothing you can give her at home to treat an ear infection, the medications needed to treat them are available by prescription only from the vet. I would take Bella into a vet today or tomorrow. The vet can diagnose the cause of her ear infection and can prescribe the medication needed to treat it. It's important to have any ear infection examined and treated promptly, as leaving it untreated can lead to hearing loss.

    Poor Canela! It sounds like she could have an ear infection, which can be caused by ear mites, yeast, or bacteria. The cause needs to be diagnosed in order for her to be treated properly, and that can only be done by a vet. You need to take her into the vet in the morning to get this diagnosed and treated. This is important to do because leaving it untreated can lead to hearing loss. I hope this helps!
