hi everybody! im new here. I hope im posting in the right category i chose Health. Didnt know if i should have chose Grooming. I came to get help with my Frenchies skin. He had such a beautiful coat for years and he has been getting bald spots since the summer. I'm attaching a picture, hopefully someone else can recognize the spot and let me know whats going on. They are usually yellowish or blackish colored around the circumference. He is on Cephalexine antibiotic. He had a steriod shot a few days ago. He is bathed with Chlorhexidine/Ketoconazole shampoo. and we switched his food today from Natural Balance Bison and Sweet potato to Wellness Whitefish and sweet potato. A friend suggested trying a fish food. Wishing everyone a nice Christmas and New Year!
