The only if you can call it a trick my bernese have mastered are:
One of my girls has taught herself how to push the peddle on my bin in the kitchen and help herself to the contents! :D
My other girl can talk, well you talk to her or tell her to lye down and she replies in what we can only describe as 'chew backer' from Star Wars! It is very entertaining and she know it!
My old boy who is now 8 years, has not really got any tricks, but I suppose the only thing he can do is steel the hearts off anyone that meets him with his charms :P
