Many dogs like Frank have allergies. They fall into four main categories: fleas, food, thyroid conditions or environmental allergies. The key is to go through and systematically rule out each one. If none of the diets seem to be helping, I would recommend to try a special hydrolyzed protein diet as this is like an elimination diet. If that does not seem to be helping then I would bet Frank does not have food allergies. Make sure Frank is on an oral flea preventative like Comfortis as this will ensure that fleas are not a problem. To determine his thyroid levels he would need a blood test. Lastly environmental allergies can be the most challenging to diagnose and there are many different treatment options available. If his skin is breaking out that bad and oral antihistamines are not helping, take him into the veterinarian for further treatment. I hope Frank's starts feeling better soon.
