"A Tom Doherty Associates book."

Series information from Goodreads.

Chet the dog ... and his human partner, P.I. Bernie Little, are greeted with a shocking sight at hydrologist Wendell Nero's trailer. The scientist met with a violent end just before they arrived--and before he could reveal the purpose of their meeting. Is his death a random robbery, as the police suggest, or something more? Chet and Bernie, working for nothing more than an eight-pack of Slim Jims, are on the case, and soon they are in danger like never before. Wendell's research leads them to a struggling winemaker who has received an offer he can't refuse, and to dry places where Chet smells water where it shouldn't exist. Bernie is sure the police have pinned the murder on an innocent man--and that the killer is still out there.... -- from book jacket.
