Ein (アイン, Ain) is a Pembroke Welsh Corgi brought aboard the Bebop by Spike after a failed attempt to capture a bounty. He often shows heightened awareness of events going on around him. Over the course of the series, Ein answers the telephone, steers a car, uses the SSW, plays shogi, operates the "Brain Dream" gaming device, and generally performs tasks that an average canine would not be able to accomplish.
While the televised series only briefly hints that Ein's brain was somehow enhanced, the manga shows Ed accessing data stored in Ein's brain via a virtual reality-type interface with which she has a conversation with a human proprietor. Ein is able to "speak" to other species, as demonstrated in Session 17: "Mushroom Samba" (he speaks to a cow with a subtitled bark of "Thanks", to which the cow has a subtitled moo back of "Oh, it's no problem").
Ein initially takes a shine to Jet, but when Ed joins the crew he comes around to her as well. He follows Ed when she leaves the crew.
