Coonhound is a family of American scent hounds rather than one breed. Black and Tan, Redbone, Bluetick, Treeing Walker, American English and Plott hounds were all developed to trail raccoons at night and bay at the base of a tree until hunters arrived. Dogs listed as Coonhound are often one of these or a mix, with a short smooth coat, long ears and a deep voice.
Size runs from roughly 45 to 100 pounds, and energy varies too, so a Redbone or Walker mix may run hotter than a Black and Tan. In Bloomington, expect to build the day around a long walk with plenty of sniffing, and to keep a leash on in a city with deer and coyotes nearby. Most are friendly and sociable, but each dog's build, energy and noise level will differ.
