I believe the answer you are looking for is seborrhea...it can either be the dry variety or oily. My 2 year old yorkie mix has it and the vet says it is common in yorkies. Due to this condition, my dog has also chewed on himself and had secondary yeast infections. Once I got help from the vet for this he improved. I was bathing him every 3 days because he would get greasy and smell rancid. I can now go a week without bathing him and am working toward going longer. The vet told me that although he has this condition, that by me bathing him so often it causes his body to make even more oil. I normally keep him dressed in a tshirt and that seems to help with him getting the rancid odor. It also keeps dirt from getting on him and sticking to his hair. I hope this helps! Before I forget, the vet did recommend quality food which he was already eating so she ruled out food. In fact, Raley has been seen by 2 separate veterinarians that gave him the same diagnosis!
Good luck!!
