American Cocker Spaniel

Hi, Kim and Cole!   I have had a lot of success treating allergies using alternative methods.  I've worked with several veterinarians over the last 25 years  who practiced holistically.   In every case I changed the dog's diet to one that I prepared myself on their advice.  The diet had no preservatives or additives in it.  I did use supplements including olive oil, Vit C, multi VitBs and a general multivitamin.   Mineral oil, if that is what you are using, is not intended as food.  Olive oil is a good supplement, however.  

If you could find yourself a holistic veterinarian - ones that use alternative methods such as homeopathy or acupuncture - you might find success.  Allergies are treatable, but they require some effort...

good luck
