k, i know i look up the information, but here you get personal experiences, i found a picture of one and thought it was so cute,. im now interested in getting one in a few years, how big do they get? what were they bred for? are they natoriously (sp?) dificult to train? how much activity do they need? how much mental stimulation do they need? do they need other companions? do they need to be inside dogs? do they tend to be overly agressive or nippy? even if they need lots of excercise, training, care, stimulation, time and effort, it wont change my mind if i decide on one, all my dogs willl have a HUGE amount of excercise, very little time left alone and very good training... just interested in them because i saw a picture on http://www.awlqld.com.au/rehoming.htm i fell in love with "charles" a little black, white and tan tennterfield terrier.
