If you ask Ty to go get the monkey, and he's feeling playful, he will sometimes find it and bring it to you. If you ask Ty where the pancakes are, he will run as close as he can to wherever they are and start whining like "right there, man! right there!" That's about the extent of what Ty will find for you on command.
Zoey has many more interests as well as the ability to make it clear that she has no interest in something. If I ask her where the monkey is, sometimes she will look over to where Ty normally puts it. She'll look in the direction of the toy, look at me and do the dog equivalent of rolling her eyes.
I can usually get her to look in the direction of things she knows, likes, or in the case of flies, absolutely hates. I'll say "Zoey, where's Smokey" or "where's dinner" and she'll look at what I ask her to, and then look back at me like she's saying "don't patronize me, Pet, we both know damn well where Smokey is."
The biggest reaction I usually get out of her is when there's a flying insect buzzing around. I'll say "where's the fly, Zo Zo" and her eyes will get wide, and she will scan the area. Sometimes I can point and say "there's the fly! get it!" and she will race over to see where I'm pointing.
Just now she jumped into my lap, and I said "where's the fly Zo Zo?" and she looked around the room, frowned, put her ears down and looked at me like she was saying "that's a very good question, Pet."
