A thick, itchy rash in a dog's armpit, especially in humid conditions, often points to a 'hot spot' (acute moist dermatitis) or a yeast infection. These areas are prone to moisture and friction, creating a perfect breeding ground for bacteria or yeast once the skin barrier is compromised, often by allergic itching. It's often very uncomfortable for your dog. Cleaning the area gently, keeping it dry, and preventing your dog from licking/chewing are initial steps. However, these usually require veterinary attention for proper diagnosis and treatment, which might include antibiotics, antifungals, or anti-itch medication. Speak to Dial A Vet via a video consult should you need further guidance.
