There 
were two Top Dog labels. This one, based in Louisville, Kentucky in 1966 and 1967 had nine releases, all with 2300 series catalog numbers. It was owned by Ray Allen (Floyd Lewellyn) and Hardy Martin as were Boss, Bridges, Jam, Rondo and Tilt.
The Louisville Top Dog label had some good releases, like the Keyes “She’s the One”, the Merseybeats U.S.A. “Nobody Loves Me That Way”, and two bands I’ve covered on this site, the Rugbys and the Nite Owls.

Top Dog Louisville discography from 45rpmrecords.com. Thanks to Jeff Lemlich for help with the Michigan Top Dog discography.
the B side on you’ll come back is…. Nobody does me that way… it is also the B side of 30 second lover. There are different band members on 30 second lover. Terry Adams only plays on… stop look and listen…. he was only in the Mersey beats for the summer of 1966.
I once had a mispressing of one of the Camel Drivers singles on Top Dog (think it was “Sunday Morning Six O’Clock”). Forget which side had the error but it played “Eight Day Blues” by Sweet Cherry. So keep that in mind if you are thumbing thru boxes of records … you might luck out and get one side of that coveted Michigan ‘60s punk monster.
