The two breeds are very similar in terms of size and coat care. Not so sure as far as health problems go. Maltese tend to cost more because they're not quite as common as yorkies (in my area, at least). Really, I dont think anyone can help you choose which is best or whatever. Do research into each breed individually by reading books or articles on the internet and make your own decision :)
Oh and this is a discussion forum, not a chat room. Please give at least a fewhours for people to read and post responses to your topics. Not 2-5 minutes :P People don't constantly refresh the site every 30 seconds looking for new topics (well.. I don't anyway) they just pop in now and again throughout the day to see what's new and respond as they do

Funny...I had the same dilema last year. Both of these breeds are indeed very similar. Yorkies were actually thought to have evolved from crossing a Maltese with various terriers. As for health problems both have very similar concerns such as luxating patella and liver shunt to name just two. As for grooming. Both are single coat and don't shed, of course that means they require regular (as in daily) brushing to keep their coats mat free and to be trimmed every 6-8 weeks. Maltese are always white so keeping them always looking clean and tidy is probably more of a challenge depending on your lifestyle. Yorkies can be high energy dogs not as high energy as say a Jack Russel though. They are really oblivious to their small size and are frequently called "a big dog in a little dog body" Both can be yappy but from what I read Yorkies more so than Maltese. Do your research. Go to the library and take out some good books on both breeds. Go online and look up both breeds and make an educated decision. Both of these breeds have a life expectancy of 15-16 yrs so be well informed on what to expect. Take into consideration their small size if there are really young children in the house. Even an accidental drop from the height of a 4 yr old can easily break a leg.
