All I have to say is AWESOME!
I've had 2 shih-tzu's growing up. And I gotta say, I will NEVER get another breed of dog other than shih-tzu's. They are simply the best.
One thing I've leared from both dogs, the first which died in a horrible drowning accident at the age of 6, and the 2nd which is still alive and well at the age of 13 is, Shi-Tzu's are tremendous food mongers. They will gladly kill you if it means they will get ONE PIECE of meat. Also, like the guy in the movie SEVEN who ate himself to death on Franco American Spaghetti, Shi-tzus will eat themselves to death.
That being said, the are stiill the best, most loyal, extremely low maitenence dog around. You can feed and water them, let them outside to plss and crap, then leave the house for a good 12 hours plus and theyll just lay around and sleep. They are basically lazy food mongers, also my favorite breed of dog.
