We have a boxer lab mix who tends to be a bit high-strung and has allergies. We stopped dog food and make our own. We also swab the ear with (diluted)cider vinegar and use essential oils (very diluted ) He is on belladonna and acidophilus, the flair ups seem to be worse after sleeping and eating. This came on after we got a new rabbit. He was not in good shape but I did not find mites.
Any suggestions would be great.
