Maizey and Mac (they're brother and sister Cairn Terriers) can be best friends one minute, and then the next snarling and at each other's throats. But at the end of the day, they're best friends and they need to know where each other are 24/7. Maizey is dominant so she's usually the instagator, however Mac can handle himself and sometimes is just so overbearring.
On that note, I use to bite, growl, and pull my brother's hair out all that time!
