I thought combing the dogs would help too. I was looking for lice, ticks, etc. Their skin looks good no flakiness. They get combed out often. One has long thick hair & the other short thick hair & their coats have a silky feel to them. We have a wood stove too & I have not ever noticed dryness or dandier in their coats over the winter months. They can sleep in the sunroom which is like an ice box in the winter during the nights. The olive oil sounds good to add to their dry dog food diet.
