[YEA] One of my German Shepherds has an immune deficiency. I have tried everything natural under the sun but, will not resort to pharmaceuticals. I feed raw, organic, no grains. ACV in water. Still biting, itchy & scabby. One day I was desperate to find a solution for her raw skin. I mixed up about a 1/4 cup of organic extra virgin coconut oil & about 6 drops of ingestable Four Thieves oil blend. I rubbed it in lightly on all the areas affected. The Four Thieves I use is a well known brand, easily found on the Internet that can be ingested. Some are only for topical use, so be careful. I would not use on cats. It calmed the areas immediately. Redness disappeared. By the next day scabs were falling off. I now do this twice a day. She actually nudges me to the kitchen for her coconut rub. Though I alternate omega 3 fish oil, coconut oil, ground flax or oil, EVOO, chia, something in her system seems to resist utilizing the ingested oils. I have started adding digestive enzymes to her food to add in breaking down fats. If someone has experienced this same problem I would appreciate feedback.
