Do Pugs make good watch dogs or guard dogs?
*Not usually. Some pugs may alert you that someone is nearby by barking gently (Pugs don’t bark loudly, in general, because it’s muffled by the lips), but most Pugs are more interested in greeting new people rather than scaring them off. The look of the Pug often will scare people – especially if you have a Bullmastiff in the yard too. Then you can just say that the Pug is a puppy and it grows up into the Bullmastiff (sorry, that’s Pug humor).
Not usually but some Pugs may alert you that someone is nearby by barking gently (Pugs are not known to bark loudly, in general, because it is muffled by the lips). They are actually more interested in greeting new people rather than scaring them off. Thus, they are the ones easily stolen rather than be the ones to prevent the event. There, too, have been reports that Pugs make good earthquake forecasters as they have been known to circle a lot and act queerly minutes before an earth shake!
