Catnip is to cats as _____ is for dogs?

I went down to the humane society yesterday with some catnip. One cat reacted like she was stoned. The other cat went crazy, Reefer Madness-style. Is there anything that affects dogs in a similar way?

Snausages!

Not really. Catnip has a unique neurological effect on cats (including some but not all wild species). I am not aware of any similar substance for dogs (or else pet stores would carry it).

Aniseed. According to Bertie Wooster.
I detest aniseed.

Catpoop

Goose shit. My dog smells it, rolls in it, rubs a shoulder into it, and thinks it is candy.

A pat on the head from a human being.

Smelling ass. They seem to really enjoy that.

A red laser beam.

Yeah, I was gonna say shit when I saw the thread title, but it really doesn’t make them reefer madness like, they just like rolling in it.
