Sadie is the stranger of my two, I think.
First off, she has a thing for laundry. If there are socks, shirts, whatever on the ground, she will go around collecting them. It sounds fairly normal for a retriever, except for the fact that if we're at someone else's door talking and she looks in and sees laundry to collect, she will go in and pick it all up. It's like she's on a mission: No junk on the floor as long as she's around.
She also loves to rub her head in things that smell like me. If I put my towel down on the bed after taking a shower, she will immediately jump up on the bed and roll her face in it until she falls over. Then she rolls around on her back like a madwoman, snorting and shoving her head into the towel as hard as she can.
She loves showering with me and loves being dried just as much as getting wet. You can see her get sad if she jumps out of the shower before I'm ready and no one is there to dry her.
She also has a thing for stuffed bears. I don't know how she knows they are bears, but she thinks that they are her babies. Every now and then, she'll "adopt" a stuffed duck or hedgehog, but for the most part, her little brood is a bear-only group.
Sadie doesn't like her leash dragging around either. If for some reason it is still on and no one is holding the other end, she will carefully fold it up in her mouth and carry it around, instead of letting it drag around behind her.
Riley likes to grumble to talk. He also likes to cuddle-like fully spoon a person. He will lay with one front arm over your neck and a back leg over your legs, like a person would spoon someone. He thinks he can "talk" to thunder, too. And he has to sit before you can put his gentle leader on. He gets kind of annoyed if you don't let him sit down and pose first.
