Thank you Nancy, I do have a conditioner and we are in CT so our heater has been on but we have radiators so not forced air.
I would give him a bath to re-rinse and re-condition but he had his lyme vaccine today and the poor guy is not feeling too well.
I will look into the flax seed

Do you grind the seeds? Sheldon is on dry food only so I don't know how the flax seeds would work with his food. Some one mentioned they add some oil, maybe coconut to the dry food?
Thanks again for your suggestions!
