I have a (just turned) 1 year old German Shepard dog who has recently developed a rash (please see pictures) on her stomach and chest area. She itches it a lot and is constantly eating at her fur. She is outdoors quite a bit as I take her on a lot of hikes and walks through forests which she loves. I work in a restaurant and I bring home leftover meat (mostly steaks and lamb, lucky her eh!) but she sometimes eats commercial dog food too (Ingredients found below). Any help is greatly appreciated. Thanks in advance!
