They are usually very good with children, even toddlers. Coonhounds love children, usually, and can make wonderful companions for lonely ones. They are very affectionate, and can take all the petting you can dish out. They like to be talked to. At the same time, they are usually not very demanding, and are content to lie at your feet.
Coonhounds are very intelligent, and have inventive minds.
I enjoy watching them figuring things out. Although they have a lot of energy, they also have relaxed and tolerant attitudes. Once trained, you can take them anywhere, and they will usually be fine, not to mention charming the socks off people. They like to communicate. This is another reason to train your hound - until they learn some manners, they communicate by jumping up, putting their noses in inappropriate places, etc.
