Mmmm. Hills Z/D may not have any
common allergens (everything is a potential allergen), but it does have carcinogenic preservatives - BHA and Ethoxyquin. The main ingredient is potato starch...
There are
many foods out there made for dogs with allergy problems, most of them much better quality than Hills. Wellness' Simple Solutions and Fromms come to mind as premium foods, but there are plenty of others.
I would note though, that Eukanuba is also a rather nasty dog food that contains a LOT of common allergens. The most common culprits are the difficult-to-digest grains such as corn and wheat, with things like beet pulp, brewers yeast, and artificial flavours following closely behind. Since Eukanuba contains *all* of these things, it really isn't a surprise that your pup may have been allergic to something - or several things - in that food. Rather than head straight for a food made for dogs who are highly allergic to many things, I'd first try a premium food that simply doesn't contain those cheap and nasty ingredients that commonly cause problems.

You should also note that demodectic mange is an
immune system problem. All dogs have the demodex mite - but it is only those who have suppressed or compromised immune systems who develop mange. The best thing you can do for your dog if it is starting to develop mange is to boost his immune system. Feeding a premium quality food is a very good start
