For about a month now Belle has been shedding like crazy. Before this she rarely dropped any hair so this has been a big change. I'm assuming it's from the season change?? She has been itching a good bit more and today I noticed two tiny spots on her coat where the hair is thin. The skin is not red and it's not flaky. Any ideas? We swapped her to Fromm from Blue Buffalo about a week before all of this happened. Does this sound like typical seasonal issues or should I examine her food more closely? She's on the pork and applesauce. She also gets coconut oil and greek yogurt daily.
