Casey basically throws herself at anyone who comes into the house, and then circles around and around their feet while licking their feet/legs/shoes/whatever she can get. She's a shameless attention whore. I've trained her to sit in an open-top box at our front door (with 3 sides, a fourth removed so she can get in) and wait until people come into the house and actually take their shoes off/walked in before she accosts them, but with the noises she makes while "waiting" in the box, you'd think making her wait 1 minute to greet people is a death sentence. I don't think she realizes she's a tripping hazard, lol.
Do your dogs throw themselves at people when they come to your house? Have you trained your dog to greet people when they come to your door? What did you do? How do they act/react?
