I have three dogs:
The "alpha" dog: A toothless Yorkshire Terrier who bites... errr... gums the other two dogs' paws if they get in her way. She also steals their food from right under their noses.
The "social" dog: A timid Chihuahua who just wants the other two dogs to LOVE her and smell of her. A lot. She also likes to hide under things.
The "big baby" dog: A Golden Retriever (4 years old) who still thinks he's a puppy. He loves stuffed animals, but they have to be plush, and they have to squeak. Anything different, and he wishes them into the cornfield.
The only one that might fetch a frisbee would be the Golden, but he doesn't seem to like plastic things in his mouth. He will fetch one of his stuffed animals, after you throw it, and after he tosses it in the air, and after he spins around in circles acting like he doesn't know where he tossed it...
The Golden is also afraid of "Thundermonsters" and "Windmonsters" and tries to hide under my desk when a storm rolls in. I feel so protected.
