say it caninamente!

From an 1863 Spanish/English dictionary compiled by Mariano Velázquez de la Cadena:

CANINAME'N'TE, can-in-ahmen'-tay, ad. In a passionate, snarling manner; like a dog.

Which was cheek by jowl with the following useful but not at all romantic term:

CANINE'KO, can-tn-tr'-o, tm. One who gathers the excrements of dogs for the use of tan-yards.
