Bored hounds will find a way to occupy themselves. You will probably not enjoy the results, which can range from climbing fences and getting into the neighbor's garbage, to the complete destruction of your sofa or your landscaping. If you don't have the time to do something fun with your dog every day, you don't want a Coonhound. I do not adopt Coonhounds out to homes where they will left alone while the owner works. There are breeds that, once trained, can tolerate this perfectly well.
All dogs are pack animals, and want to be part of a group.
Coonhounds are more so than most. To leave one entirely alone is cruelty. I know that have been left alone all day rapidly became either escape artists, major diggers, or boredom barkers. If you would need to leave your dog home alone all day, you don't want a Coonhound. Speaking of barking, Coonhounds are loud.
