@Patty:
Welcome to the forum.
I've never seen a rat terrier in the UK - I've noted from the forum that they seem to get on well with basenjis
Rat Terriors are hyper, jump constantaly, will lick you to death, and bark like crazy at any noise they hear. BUT as soon as my Dixie see's what the noise actually is, it usually scares her and she goes running away from it. She is really easy going and my basenji just takes control of everything. The only time they don't get along is when I give them a chew bone or something. I have learned to separate them when I do to avoid any problems
