Pork, Rabbit, Venison, Boar, Buffalo, all are good options. A good probiotic is a must, Genestra has a good one, no allergens no dairy, kelp or other fungus for a dog to react to. If your dog reacts to molds stay away from plant enzymes for now. Seacure is a fish based l glutamine that repairs the intestinal lining and gives nourishment easily tolerated by IBD dogs and allergy dogs.
Re local allergies, yes they can change with a move, anything outdoor consider local bee pollen granules. It can take a month or two but they work wonders. Start literally at one teeny granule wait a day, add two slowly work up to a couple tsps. AGAIN research the above, you have to start slow with all, only ONE supplement a week, and especially even if it seems tedious literally one granule of the pollen. It can take a month to work up to dose give or take and another few weeks to ease reactions.
Do you bathe your pup regularly? Again with allergies, at very least wiping down with a damp cloth face, feet EVERY time they come in is a must. If have carpet again in your new place and do not wish to lift up there are some really good dust mite sprays.
Lastly yes a good holistic doctor, do the research, call ask questions, if they do not answer initially and easily move to next can help a great deal. An immune modulator something to balance is also something you would wish to consider. Depending on the sensitivities there are thymus glandulars, colostrum among others.
If you start on raw... as long as there is no worsening in the first week... you want to stay on the one protein only that includes all treats etc, barring a probiotic for four weeks minimum, only then try one new one a week and watch. I am a member of an international allergy Facebook forum. Many great ideas, feedback from conventional and holistic food companies, vets and people. It is tough, and takes time, and every dog is individual but it can be doable. Yes steroids should be a last option and Atopica suppresses the immune. Lastly, have you tried Zyrtec or Benadryl, safer than steroids for sure to ease histamine reaction. Natural alternatives, Vitamin C, Quercitin, Stinging Nettle.
