Since the day we brought both our pups home they have greeted us with a toy or whatever anytime we walk in the door. We could be gone 3 minutes and they wiggle, grab a toy and run over to us with the toy in thier mouth.
If they can't find a toy quick enough, they'll get anything....newspaper, pen, brush it has to be something. Not one time, have the greeted us without something in their mouth!!! They are 2 & 3 years old now and still do this. When were gone for a few hours, they will go potty ( pee and poop) with the toy in their mouths.....it's so funny!!! They have gotten laughed at plenty of times from the drive-by neighbors.
Also, Bosco will circle the dinning room table when we get home. He's kidney beaning with a toy in his mouth and has to walk around the dining room table 2 times. During dinner time...he circles the kitchen island and then sits for his food. Has always done this!!!
