Dance is obsessed with my mom's nail polish and nail polish remover (which she tries to use outside if it's nice out). And her nail file. And apparently peppermint essential oil, too. Basically, if it smells strong enough that you don't really want to be in the same room with it for long, Dance is all over it. I have no idea why. She repeatedly will come up, sniff, make a funny face, and do it over and over all the while her tail is going a mile a minute and she looks super happy. But it can't be good for her so we do tell her to knock it off and go away. At which point she does and then just stares.
And if my mom and I are home together and we're going somewhere, they all get stupid excited when we put our shoes and jackets on. Because after all, why else would we be going somewhere together without them! In all honesty, I don't even know why they think that as we do go places together a lot of times without them. But they're ever so hopeful.
Dance is enthralled with beer also. Nobody in my house drinks very often, but if others come over and have a beer, Dance wants it so bad. The Dobermans like it too, but they're less moochy over all than Dance is and are not obsessive about it.
I'm not really sure what else gets them excited. Most of the things that get them excited are dog things.
