I think there's has been some misunderstanding with regards to 'Dog Style' , as a working title for 'Comming Down Your Way' .
According to Schwann 's December 1976 :
Three Dog Night - Dog Style Dunhill 50198 vinyl
It would seem that Three Dog Night -Dog Style , did exist.View attachment 113851
There's no confusion, Dog Style made it to test pressing and no further before being shelved in 1974. They dropped a few songs, recorded a few new ones and released it in 1975 as Coming Down Your Way. Just because some catalog lists it doesn't mean it was released, quad catalogs are full of this kind of thing.
