What's causing my dog's itchy skin patch under her harness?

Updated On September 23rd, 2025

Hello, I came upon this patch on my dogs skin below her neck area where the harness is only covered by. I've noticed itching, but I thought it was due to more being able to reach that area since it was covered. I'm not sure if it's fleas/ticks or another skin problem. Please help me out to determine the best solution for my fur baby. Thank you kindly.

Poor pup! This scratching can be caused by fleas, mites, ringworm, or allergies. If she isn't up to date on her flea treatment, I can give you one for her. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If she is up to date on her flea treatment, I recommend taking her into the vet for an exam today or tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I hope this helps!
