Dog losing hair, scratching, and smells bad after flea infestation?

Question

What could be the underlying issue with these patches of missing hair? Parts of his legs, a lot above his tail, his stomach, and mostly his back. We just got over a flea infestation, and most fleas are gone. The other dog has same type of fur and same environment, but doesn't show these signs; confusing. He continues to flea bite, scratch, and some areas seem to have open wounds. Had a bath, but still smells. Whats going on? Ideas? Do not just recommend a vet! Thank you!

These lesions are typical of an allergy. Since you are still battling fleas it is most likely a flea allergy. Your other dog does not show signs as he is not allergic to the fleas like Raider is. An odor suggest there is a secondary bacterial or yeast infection on the skin from the scratching. Weekly bathes in a medicated shampoo is helpful to soothe and clean the skin. You can continue to use flea medication to treat the fleas both on the dogs and the environment also to help. You can give an over the counter anti histamine such as bendaryl to help the redness and inflammation. You can apply cortisone cream to the spot also There is not many other options at home other than those. Your vet can address the areas and provide stronger anti itch/allergy medication along with antibactics or antifungals if needed.
