It depends! Personalities differ from one dog to the next. Elkhounds have a strong hunting instinct and will bark for hours at a treed squirrel, or raccoon, or similar. But they do not tend to make much noise at all when visitors arrive on the yard, unless it’s at night and the visitors act in ways that the dog finds unsettling (sudden or strange noises, etc). We have various visitors make comments on how quiet our dogs are when they arrive.
An Elkhound left outside at night may answer neighbourhood dogs, loudly challenge passing coyotes, or take to barking at some strange nocturnal noise; so if you have close neighbours, and you want to maintain your relationship with them, as we all should, you will probably want to take your Elkhound in, or lock him in a kennel, for the night.
A new puppy will tend to whine, and bark shrilly, when left alone for periods of time. Having another dog to socialize with, or lots of interaction time with you, helps a lot.
