Please help me with my yorkie...she is sweating

Hi I have a yorkshire Terrier....was given to my by a freind.  I know from reading up on them that are not suposed to sweat.  Mine does.  I give her a bath most every week.  But, to no avail she is still sweating.  There is a strong oder too.  I just don't know what can be wrong?  Can you please tell me if this is somethig I can take care of or is this a visit to the vet?

Dogs have two types of sweat glands.  Eccrine glands are found on the bottoms of the paws, and apocrine glands are found among the hair follicles.  Dogs do not thermoregulate themselves by sweating through the apocrine glands, instead these glands secrete pheromones that are used as a means of communication with other dogs.  Also, the amount of "sweat" produced by the apocrine glands should be a minute amount, certainly not enough that it would appear as though the dog was sweating.  
Dogs thermoregulate themselves by panting and by sweating through their paw pads.  Any moisture that is found on her body is not sweat, even though it might have the appearance of sweat.

I would say that if your yorkie is producing enough pheromones to make her coat wet, or even enough to be noticeable, there is something odd going on with her endocrine system that needs to be addressed.  She could just be a dog that produces an abundance of pheromones.  It could be something is peculiar to just her, or it could be an actual medical problem, but I would have a vet be the one to make that determination.

Is she spayed?  How old is she?
