In the last week I have noticed that Angel has started to lose some fur resulting in patches showing skin. The skin is not sore or anything and she has not had fleas and can't think why she is losing her fur. Do you think it could be because we have changed her diet? We switched from kibble to Raw about two weeks ago. I've already seen improvements as her skin is less flaky (she suffered badly with dandruff) but she did have a nice thick coat and now she has patches Here are some pictures of the two patches.
