Why is my dog's ear red, swollen with liquid, and skin breaking out?

Poor girl. This may be an infected mass or even a cyst. I would recommend having your vet take samples from this to be certain as to what is inside and perhaps the vet can also carefully drain it using a needle and syringe. In the meantime you can do alternating cold and warm compresses on the area for 5-10 minutes twice a day, if tolerated. Otherwise, your vet will need to get involved here to get this resolved. Best wishes with your pet Stormie and I hope you can get this source of discomfort taken care of soon for her. Take care.

Isabella's skin looks horrible, and this could be a severe skin infection. The discharge from her eye could be due to an eye infection. Her skin is really bad and you cannot treat this at home. Please take her into a vet immediately.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! There are a lot of things redness and swelling could indicate. Sometimes it means there is an infection present such as a bacterial infection. It could indicate an underlying allergy of some sort (environmental, contact allergy, or to food). Redness around the ears especially could mean an ear infection is present. My advice would be to take her into see her veterinarian so this can be evaluated. Your veterinarian may check her ears for an infection and may recommend antibiotics or certain topical medications depending on what your vet suspects.

Please get trish assessed as soon as possible by your vet to identify and treat the underlying cause as well as any infections which have developed in the damaged skin. Your vet may wish to do tests to identify any mites which may be present under the skin

Ouch, poor Remington! You are correct - most ear infections in dogs stem from underlying allergies. Allergy issues in dogs mostly cause skin problems and ears are skin, after all. The allergies could be associated with environmental issues (atopy), food allergies or flea allergies. I can certainly see the discharge and swelling in Remington's ear. Her excessive scratching obviously indicates that she's quite uncomfortable. Allergy issues cause dogs to itch, which damages the skin barrier and then leads to ear infections from an overgrowth of yeast and/or bacteria in the ear canal. There are no effective over the counter treatments for ear infections. At this point, I recommend taking Remington to her vet for an exam and ear cytology. Your vet will be able to look at her ear discharge under a microscope to determine the type of infection present, and will then prescribe an appropriate medication based on those results. Until you get to the vet, consider putting an e-collar (cone) on Remington to prevent her from causing further damage to hear ears. I hope this helps and that she's feeling better soon!

I am so sorry to hear that Gizmo's ear is bothering her. From what you are describing I believe she has an ear infection, and has been scratching at her ear causing the changes you observe. Ear infections in dogs can be very difficult to manage, and are very common. Though cleaning may help prevent ear infections ruins, it won't treat an ear infection that is present. Antibiotics are needed. Unfortunately, there aren't any medications over the counter which would be helpful at this stage. Outer ear infections can progress to inner ear infections. Inner ear infections are very difficult to treat, are very painful and have serious potential complications, such as hearing loss and problems with balance. I would suggest a trip to the vet as soon as you can. The vet will use a tool to look into Gizmo's ears, and may take a swab of the infected ear and send it away for analysis, so that the exact pathogens causing the infection can be identified and therefore a specific antibiotic can be used. 

I hope that this answer was helpful, and more importantly that Gizmo's ear gets better soon. Warmest regards to you both.

It sounds like she has a bacterial skin infection so she should be examined by a vet for treatment. Your vet can shave the area, flush and clean the area, and then prescribe an antibiotic and anti-inflammatory, if needed, to help treat.
