Darn my post last night didn't 'stick'.
The bad news is it only takes ONE single, solitary flea -- just one -- to bite and die!! So if you're using Frontline or Advantage and the nasty thing got on the dog, bit him ONCE and then died it can still cause flea allergy dermatitis. The dog is actually allergic to the flea's 'spit'. (saliva) It's a toxin to allergic dogs and it will literally set them up for months and months of agony and sore skin.
When it *starts* (and you may not know because the dog likely has had it before this) it is at the base of the tail, and it will creep forward and down the legs -- but in successive times it can pretty much break out anywhere. It's a sore scabby thing rather than just a pimple or hot spot -- I don't know why flea allergy dermatitis is so 'scabby' but it is. They'll get scabs where they can't even reach TO bite and itch and scratch.
So bottom line you have to keep a good Flea preventive on them, and NOT something like Revolution or Biospot where the flea has to bite TO die. Frontline or Advantage are as good as it gets for these dogs and can help enormously.
And sometimes being proactive and spraying the dogs legs with something *before* you go out (so the fleas are actually repelled -- and an herbal spray can sometimes be wonderful here) so the fleas aren't as likely to jump on. Just because you don't have fleas in your home/apartment doesn't mean that bush he peed on didn't have one waiting for something warm-blooded to walk by so it could jump on.
Real atopic allergies typically wouldn't begin by that age (altho demodectic mange would but the spots are in the wrong spot unless he was majorly infected with demodex before you got him) -- let's hope it's NOT regular allergies -- regular allergies that manifested that badly by that age would be really super bad by the time the dog was mature. Dog allergies increase as they age, unlike humans who tend to 'grow out of' them.
