In response to your question the skin turning black is called "hyperpigmentation." This usually occurs by inflammatory cells (macrophages) releasing a chemical called "melanin." When there is a long standing inflammatory response like an infection, allergies, etc. the cells release melanin causing the skin to turn black. The color change is not malignant just a consequence of the inflammation.
It sounds from the history that your dog may have an underlying allergy (food or environmental). The first place to start is doing a food trial during 6-8 weeks. This is what you can do:

1- Change the diet to a prescription food called Hill's z/d or a grain free diet with a different source of protein then what he normally has in the past. For example: Taste of Wild Salmon. When on this diet he should not eat anything else or he will not improve. Needs to be on this diet for 6-8 weeks before you see significant improvement.

2- Start her on Benadryl (diphenhydramine) 1mg for every pound body weight every 12 hours. For example if he weighs 10 lbs he will require 10mg every 12 hours.

3- Supplement with Fish Oil, 20mg of EPA for every pound body weight once a day, long term.

Hope the above helps, if you have additional questions I will be glad to answer them.

ok, well it takes at least 6 weeks after changing the diet to see significant changes; make certain she does not eat anything else or table food. If after 6 weeks you do not see any improvement consider trying a hypoallergenic diet like hill's z/d, this diet is made with special protein that does not cause allergies. Continue on Benadryl and start the fish oil.
