Using an inexpensive topical flea product that you buy at Walmart or a supermarket such as BioSpot or Zodiac Spot On would be better than not using any flea product at all!
As far as the food goes, you won’t find a hypoallergenic dog foods at the supermarket, you’d need to look at pet stores or specialty feed stores. You need to find a food with a dog food with different protein and carbohydrate source that what he’s currently eating. You should try keeping your dog on an “elimination” diet for 8-10 weeks to see if his itchy symptoms improve. In an elimination diet, the dog is fed a food that has a protein and carbohydrate source he’s never had before. There are many over the counter foods you can use, for this purpose. I’ll suggest a few further down. Your dog’s elimination diet should not contain:
• Wheat, barley, rye – ALL of them. (including bread, snack crackers, treats, wheat/gluten, etc.)
• Dairy products – ALL of them. (including milk, cheese, whey, casein, dried skim milk, etc.)
• Soy – ALL forms
• Corn- ALL forms (including corn gluten meal)
• Artificial preservatives and colors
• Beef and fish – (only if allergy symptoms are present/persist for longer than 8-10 weeks. These are “secondary” allergies.)
By eliminating the above items, you will be taking care of at least 80% of all food allergens and all three of the major sources of food intolerance (gluten in grains, casein in dairy, and soy protein.)
This diet must be strictly adhered to, it includes ALL foods, including TREATS and TABLE FOOD! Be strict! Food allergies can be very sensitive conditions and the least amount of the offending substance can trigger reactions that can last for days. Be creative in finding safe treats for your dog those that MATCH the diet rules. This will be a lot harder on you than your dog.
Giving your dog an essential fatty acid supplement can also help suppress itching. Arachidonic acid is stored in cell membranes and released when the cell is damaged, it then combines with certain enzymes causing inflammation and itching. Essential fatty acids combat this reaction because the essential fatty acids combine with the enzymes, making them less available to bind with arachidonic acid, reducing the inflammation and itching. Your dog would need to be given an essential fatty acid supplement daily for at least a month before you see it’s beneficial effects.
