The second thing "within" that you need to be sure is taken care of is internal parasites. Worms of any kind -- tape, round, hook, etc. take up the nutrients that should be going to the dog. Tape especially if you have had fleas at all is probably there and you may not know it.
If everything within is okay then you need to look at the products you are
using to bath and groom your dog. Maltese should be bathed with a good
quality shampoo that is moisturizing or conditioning based and make sure you
avoid those that strip the coat -- like disk washing detergent or
clarilfying shampoos (unless you need to get something like oil out). And
then you need to follow the shampoo with a conditioner. And finally, when
you brush you should use some sort of conditioiner/rinse diluted in a spray
bottle to aid in brushing.
