My Toki used to be really quiet and only barked 3 times when someone was at the door. Every month goes by his getting more protective and barks until I get up to see who it is or he won't stop barking. That is fine because I think that's a good guard dog for a yorkie. Now the only problem I have is he barks and whines about every little thing. If his on the car he will bark or sometimes whine for nothing. And then he will bark at his toys. He never used to do this. Will he ever be the same quiet doggy? I can't stand the barking. It's driving me insane.
