Leana Beasley has faith that a dog is mans best friend.<br />Faith, a 4-year-old Rottweiler, phoned 911 when Beasley fell out of her wheelchair and barked urgently into the receiver until a dispatcher sent help. Then the service dog unlocked the front door for the police officer.<br /><br />I sensed there was a problem on the other end of the 911 call, said dispatcher Jenny Buchanan. The dog was too persistent in barking directly into the phone receiver. I knew she was trying to tell me something.<br /><br />Faith is trained to summon help by pushing a speed-dial button on the phone with her nose after taking the receiver off the hook, said her owner, Beasley, 45, who suffers grand mal seizures.<br /><br />Guided by experts at the Assistance Dog Club of Puget Sound, Beasley helped train Faith herself.<br /><br />The day of the fall, Faith had been acting very clingy, wanting to be touching me all day long, Beasley said Thursday.<br /><br />The dog, whose sensitive nose can detect changes in Beasleys body chemistry, is trained to alert her owner to impending seizures.<br /><br />But that wasnt what was happening on Sept. 7, and Faith apparently wasnt sure how to communicate the problem. During Beasleys three-week hospital stay, doctors determined her liver was not properly processing her seizure medication.
