Are Beagles vocal

Answer 1

Depends on the beagle and how well trained they are. We dog sit a beagle and she barks when people arrive at the house but not much else. When she does barks it is LOUD. They are not quiet dogs.
Yes, and the bark is very deep and hoarse sounding.

Answer 2

They are not the loudest barkers, but they can make a loud baying noise, which is what makes them poular as a hunting dog as it makes it easy for the hunter to follow them.
