My dog has a large red circle near her ear. What could it be?

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking(if any).

It seems a small trauma, which is healing fine and at the moment (looking at the pic) I cannot see any sign of infection. Disinfection can be done at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching (if any).

From the pictures, it looks like Bambina might have a hot spot or skin infection. She will need to see her veterinarian because she will need medical treatment (usually antibiotics and something for inflammation. Please do not use any over the counter medications). This can be very uncomfortable so getting her treatment is important for it to heal and her to start feeling better.

Thanks for using Petco Pet Education Center, formerly Petcoach! These could potentially represent nodules or masses that have become ulcerated. They could also be just focal patches of dermatitis. I recommend that you have Bella evaluated by your veterinarian. This is most of the time differentiated with a test called a fine needle aspirate which is easy, cheap and pain-free. Sometimes, a biopsy is required for a diagnosis. Have Bella evaluated by your veterinarian to have this test performed to try to sort out what the diagnosis is so that the best course of action can be determined. If it does not appear to be a mass on examination, they can at least do cytology of the superficial aspect and see if infected and prescribe antibiotics for it. Keeping my fingers crossed that it is something benign!

Thank you for providing a picture of Rosie's wound. It looks like she could have injured herself, leading to this red spot. I would gently clean it with warm water and antiseptic soap. Keep an eye on it, and if it gets bigger, becomes swollen, warm to the touch, or there's pus, I would take her into the vet to get treated. Best of luck, I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! If it truly was not there yesterday, this is most likely to be a bug bite (tick, mosquito, spider, bee, other), dog/cat bite (if he was wrestling with any other friends lately), or some other random trauma (crashing through a spiky bush or catching it on something). If you're unsure how long it's been there, add cyst, benign or malignant tumor, and others to the list of possibilities. I'd slap some neosporin on there twice daily and watch it. If no improvement in 3 days (or if worsening at any time), it's time to see the vet. This goes for any accompanying facial swelling, vomiting, or diarrhea, as these could be signs of serious allergic reaction. Best of luck to you and Lucky!
