Why does my dog have a rash on his chest after wearing a new harness?
Thank you for submitting your question regarding your dog. I recommend starting by bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to soothe the skin. This can help with a minor rash or irritation. You can also leave the harness off for the next few days to see if that has been contributing. If the rash spreads, is very itchy or develops pimples, then he should see his veterinarian. In this case, he could require treatment. Unfortunately, there are numerous causes of red skin. For example, allergies to something in the environment, his diet or something in the house can cause it. Infectious organisms like fleas are common in certain parts of the country. If necessary, the veterinarian will examine him, ask detailed questions about his lifestyle and history and prescribe medication as needed. I hope this information helps!
