Taylor my lab has associated the phone ringing with people coming to visit, probably b/c we let people in the front door by phone system. Whenever the phone rings he runs to the door immediately and waits for someone to come through the door. Let me tell you he's very disapointed when it's just a phone call and not company.
Also he figures the bathtub is a fantastic place to play, not only in my house but every house we go into he feels the need to go immediately to inspect the tub. At home he keeps coming to get me until I turn on the cold water tap for him. In the tub he jumps, gets a quick drink and he starts the doggy paddle. I don't put the plug in but he's figured out that if he does the doggy paddle in the running water it shoots up to get his belly wet. Kind of makes a mess sometimes but what can I say he's an only child and it is quite humerous to see this animal shooting water all over the place.
