Aww I love Terriers, and yes they can definitely be little terrors My 17 year old is half poodle and half cairn terrier. I did have a 16 year old that passed away that was half pekingese and half poodle.

My other dog is also getting old, she's 14 now and she's definitely a bratty little Jack Russell Terrier. She used to be in movies, commercials and seen on President's Choice dog food cans & bags so it sounds like she's obedient, right? Apparently that only counts for her trainer, she'll do very naughty things at home. Gotta love her though!
