Based on our experience and research, Frenchies are very moderate barkers and tend to bark only when they feel something is really worth getting excited over, such as when a stranger comes to the door, or they hear loud, strange noises. Once they know that there are no threats, they will stop their barking and immediately try to make new friends.  They are certainly not excessive barkers, such as our Yorkies and some other breeds were.

We have observed that there is also a big difference between our various Frenchies in this regard. None are excessive barkers, and some we have never heard bark, although we assume they can if they wanted to.  Some bark at things that our other Frenchies will ignore. For example, there are several large animals on our property.  A few of our Frenchies will bark at them a few times, just to let them know they are there. The rest of our Frenchies will completely ignore them or go to the fence to try to make friends, but not make a peep in the process.

We also have chickens, ducks, and rabbits on our property (we practically have a petting zoo), and some of our Frenchies will chase them and bark at them, some will give a halfhearted chase while not barking, and some will slowly approach them and try to make friends.  They are all a little different, and it is funny to watch how each of them will react to various situations.
