Our Bulldog started developing a bilateral, alopecia on her sides, also known as flank alopecia. It started as small spots that looked like pock marks, then they kept progressing until she had large, hairless patches on each of her sides. We were told they were mostly likely seasonal and due to diminished amounts of sunlight but they would mostly self resolve after a few months. The spots have, at times, started to appear to be resolving only to persist. We changed her food to a healthier brand. We are now changing her shampoo based off the recommendation of this site. Could the alopecia be caused by some sort of skin infection or bacteria? I am consider rubbing her sides with the malacetic wipes. Any thoughts or advice are much appreciated. Thank you!!!
