Welcome! I am so sorry your animal is experiencing skin issues and is most likely in a lot of pain; as any SKIN ISSUE means the body is under an amount enormous strain trying to eliminate a TOXIC OVERLOAD. Actually, ears and feet are usually the first places to show stress before the entire body.
What is happening, is the internal organs are SCREAMING for help as they are overloaded and pushing toxins away from the heart and the brain, trying to save the body as the whole system is in a lot of trouble. Parasites, of course, are another consideration, as shown in this photo.
I would be honoured to help you both. Please reach out to discover what your animal’s healing journey may look like.
