One of our guys loooooves chuckit balls. They have a bunch of different types, and he'll play with all of them, but the original ball is his favorite. When he isn't just chewing on it, he will push it with his nose and drop it off of the couch and down the steps just to chase it. It's great. We got them the medium size.
I know you said no balls, but one of our guys loves Chuckit balls. When he isn't just chewing on it, he'll push it around with his nose and make it fall off of the couch and down the steps then chase after it. And these things are indestructible. They make a bunch of different types, but his favorite is the original. We got the medium size and it's perfect.
If you have room for her to run, invest in the chuckit ball launcher. It makes throwing the ball so easy (and you don't have to get your hands all slobbery!)
