Chinese commands??? What does that mean? The commands they give are in chinese??? If so, how are you going to know them? Are you always going to be blurting out chinese to get your dog to do something?? And I agree on the guarding, you don't need to teach a lab anything about that! Yesterday, there was a bang outside and my lab started barking, really loud. That freaked me out because she doesn't bark like she did yesterday! She sounded like a rott! I went over to the door and told her good dog, and she kept it up! I wanted to make sure noone was out there, but I didn't want to let her out (if there was a person they could hurt her!) So I just kept saying sick um, woof, good dog! After 5 minutes I let her in the house (she was in a room by the door) and by now she knew noone was out there (I think), but I wanted her to keep it up so I kept going Woof!, grrrr, and she would do the same. She NEVER had any training for being a guard dog, but I think most dogs know when somethings not right and take action. :D
