I have 2 dogs one that's 10 and the other that's 4. They both seem to be getting small, flaky, dry spots like this all over the body rather suddenly. They keep scratching and licking them and the very dark black spot seems to smell. The very dark bump though is only on the legs of the older dog. Please help me figure out what I can do at home to make the spots go away ! Pet's info: Dog | Maltese | Female | unspayed | 10 years and 6 months old | 30 lbs

The first thing to do is to check for any fleas. Some can be allergic and make scratching worse. They sell Advantage and Frontline over the counter to help control fleas if needed. The odor may be from a secondary infection from all the scratching. They will likely need to go to the vet to determine if there is an infection or a separate allergy (environmental or food) causing this. All you can do at home is a regular bath once a week to help their skin and apply antibiotic ointment (neopsorin) to the areas that seem worse and have scabs. They make omega 3 fatty acid supplements for dogs that help their coat and with dry skin that might be beneficial to add.

I can't really tell from you photo if the black spots are raised or did the skin just turn black? That first photo looks like a mass/tumor on the leg..... Again, I can't really tell from the photo. I think I would try a medicated shampoo first. If there is an odor it may be a yeast skin infection (although it doesn't really look like it). I would recommend this one: https://www.amazon.com/Dechra-Miconahex-Triz-Shampoo-8-Ounce/dp/B00K4WWY3U Lather the shampoo on the coat, let it sit for 10 minutes and then rinse thoroughly. This is very important. The shampoo needs that long contact time to work effectively. Wash them 2-3 times a week until the spots/smell is gone. If no improvement in 2-3 weeks then you should take them to your vet for an exam. If that one spot is a mass/tumor you should have that checked right away as it could be a cancer. I hope this helps. Best wishes!
