How does a person go about certifying a dog as a Service Dog? I was asked by my trainer, as she wasn't sure about how. She's got a friend with a Chiwawa that alerts the wife if the husband is having a minor seizure, and they are now inquiring about getting him certified so they can take the Chiwawa everywhere with them. They are in Washington State as well, about an hour away from us. Any info is appreciated. I did find the site http://registeredservicedogs.com , is this all they need, or is there training needed before certifying? The dog is well trained, up-to-date on all shots, etc, and is a people loving dog with no aggressiveness at all. Thanks....
