>>I was feeding him Iams and he continually got bumps and light hair loss. I switched him to Canidae and it cleared up. However from time to time he gets real dry skin and his hair looks coarse. That's why i wondered if fish oil supplements would be safe or even beneficial.

There are genetic skin problems in some Dobe bloodlines, related to the dog's color. But at his age, there are natural coat changes happening, too. Dogs go through about three coats by the time they get the mature coat. A veterinary dermatology specialist is the best one to examine the dog in person, do any indicated testing, and recommend a diet that will address any genetic problem the dog has.
