do you mean find the dog as artwork on the album cover or actually on the record?
I'm going to guess actually on the record. On the Beatles 'The Lost Anthology Volume 2', you can hear 'The Wrestling Dog', being read by John Lennon. Track 9. In-between 'Can't By Me Love' and the 'Shea Stadium Intro'. Of course, I'm sure you'll let me know just off off I am in that delightful way of yours.
