A Lhasa Apso is good nervous little barker. Don't even think about coming near the house or coming near the yard without him going into a barkin' frenzy. The golden we had as kids would probably invite the guy in & show him where all the valuables were as long as he got petted.
But my wifes little chocolate colored toy poodle had to be the smartest dog I ever encountered. She had named it Prissy and when I teased the dog and said Prissy is a sarcastic way that dog actually was embarrassed and tried to hide it's head under the pillows on the sofa. Anyone that got within five feet of the front door was yapped to oblivion fer sure !
Small dogs are worth their weight as a cheap little alarm IMHO and experience.
Stay Safe ...........!
Recently found out that I need to pay more attention to his growls in the middle of the night. He may be a wuss but he is my early warning system.
I had a golden/rottie cross, he looked like a shorthaired golden on steroids. Solid gold, sweet as pie. Thought he was worthless but lovable till one day the propane guy drove in the yard without me hearing. I just heard this "help, help" in the front yard. Came out and the dog had the guy backed up against the tank truck with his jaws at full slaver at his "family jewels". Never bit him, but the guy was a white as a sheet. I called the dogs name and he licked the guys hand and came over to me and leaned on me in full "pet me" mode. Gosh I miss that dog...
