A Border Terrier will adapt itself to most enviroments.They are the easiest going of all terriers. They respond well to some training and I highly recomend a few puppy classes.
A border will mould itself to its owner. If you sit on the lounge all day so will he, if you are active he will run with you all day. Girls are a little more independent then boy's. Boys seem to devote themselves more to there owners than girls.
Borders get along with most other animals as long as they have been bought up with them or introduced to them slowly.
