Which dog has less health problems Maltese or shih tzus?

I think malteses are healthier and even have a longer lifespam compared to shih tzus living in the same conditions. This is one of the reasons why I chose a Maltese but if you really like shih tzus I can tell you that my neighbour's girl is already 9 years old and really healthy and playful, so always your care is important. Hope this helps.

My shih tzu lived a very healthy life to 17 and a half years old he was born 92 he just died this year. so i don't know what you saying about them not living long lives. he was tied as the oldest dog ive seen in his pet commentary
