The Wolf is currently being re-introduced into some areas in the United States... Probably the biggest misconception of wolves is about their size..They are not nearly as large as most people imagine.. Their thick fur gives the appearance of a greater size, but they are usually no taller than a good sized German-Shepherd. Every member of the wolf pack knows its place in the hierarchial structure of that wolf pack.. There is the ALPHA male and the ALPHA female. The ALPHA male and ALPHA female often mate for life.. Wolves become sexually mature by the age of 22 to 24 months.
