MABTR has found flax seed oil or coconut oil replenish the oils the coat/skin are missing for a nice shiny, soft coat and no more flakes.
You will see a difference in just a week and having your dog on flax seed oil or coconut oil for 30 days will make a big difference, along with a good diet.
You can find flax seed oil with omega 3 (key is it has to be 'oil', no seed or powder) at most stores. Coconut Oil can be found pretty much anywhere but we purchase at Sam's Club in bulk. You do not need the expensive stuff. For flax Seed Oil make sure once you open the bottle it goes in the fridge. Bostons get one tablespoon a day. Most will eat it right off the plate or place it over their food.
One more tip. Wipe baby oil on your dog's coat to control the flakes until the skin has completed treatment.
