My dog has been on the same type of food, BENEFUL. He gets enough food and exercise.

But, he had "Hot Spots." Red spots underneath of his hind legs.
We used a spray "Cool Skin." That worked.But, they keep comeing back if I forget to put the spray on. It doesn't seem to bother him much. So we changed his food to a more heathier food recomended by a feed store owner. He has been doing much better. The new food "Halo" is better for him, anyways. This way he gets more nutrients.

I plan on consulting a vet ASAP. But I will not be able to for a few more days.

Any suggestions as to what I can do in the time being to help with the red spots?
