Sorry about the lapse in posting !!! I didn't realize when I said that I'd get back to you, an old friend would be calling and keep me away from the computer for so long. It was nice to reconnect with them, though. Anyway, my Vet. recommended:
...an oatmeal shampoo made specifically for dogs. Get the dog wet first, then run a small trickle down his spine, then add a little more water, massage into a lather, then rinse thoroughly...then rinse again. Seemed obvious enough to me too, but he said that, besides using the wrong shampoo, residual soap residue is the leading cause of red, itchy skin in dogs (medical issues not withstanding). This may account for him seeming worse after the second bath.
...feeding a high quality dog food with an alternate source of protein, such as fish, duck, venison, bison, rabbit, etc. (lots of dogs are allergic to corn, which, as you know, is fed to chickens which is a popular ingredient in dog foods).
...avoid dog foods that list corn, corn meal, corn by-products (basically anything Corn), as one of the first 3 ingredients on the label. Instead, look for things like sweet potatoes, peas, lentils, etc.
...don't over-bathe or under-bathe. (once a month is SOP).
...if need be, treat for fleas (did I seriously just tell you that? I guess I should be reading when I transcribe!)
...give EFA's (essential fatty acids.) I switch between Omega-3's and salmon oil in capsule form, whichever's cheaper at the time.)
...give digestive enzymes (present in raw food diets (gag!), but destroyed in commercial ones from heat and processing).
...if you live in a very dry climate (or use a lot of forced air heating), buy a humidifier (for my dog !!! Really ??? People DO that?)
...if inundated with fleas, give nutritional sulfur with their food. (again with the flea thing...)
And as long as we're revisiting the whole flea thing, I use a moisturizing spray on my dog. I saw it in some dog magazine, Dog World, Dog Fancy, Doggie Doo, Dog something...I can't recall. I make it myself using 1 oz. of Alpha Keri Bath & Shower Oil (or generic equivalent) and mix it with 1 qt. of water and pour into a spray bottle. After her bath I give her a light misting, concentrating on any really bad area, and let her dry naturally. You don't rinse this off. I'm not saying it's the be all, end all in dry skin relief. But it seems to helping with the flaking, plus, it makes her smell good too...an added bonus !!!
I hesitate to even list the last one. Only because I really think that if the itch has gone so far as to need it, YOU SHOULD CONSULT WITH YOUR VET FIRST!!!
...use an antihistamine. ONLY give Diphenhydramine (trade name, Benedryl), DO NOT give your animal a decongestant or cold & flu medication, as it CAN BE TOXIC and may result in death !!!
Again, I would only use these things on the advise of a Vet., and since I lack that particular license, please, DO NOT interpret the above as a recommendation for your animal in place of an authority on animals (which I am NOT). I'm not a Vet., nor am I trying to portray myself as such. I'm just passing on general information that I've either absorbed or experienced over the years! That all.
Thank for reading such a lengthy post. I hope this will help you or someone you know that's kept awake at night by a scratching dog with an angry itch !!!
