Terrier Transgressions

I'm finally coming to terms with the fact I can speak to animals, even though the only one who ever talks back is the crabby tabby I've taken to calling Octo-Cat. What I haven't quite worked out is how to hide my secret . . .
Now one of the associates at my law firm has discovered this strange new talent of mine and insists I use it to help defend his client against a double murder charge. To make things worse, Octo-Cat has no intention of helping either of us.
Our only hope rests on a spastic Yorkie named Yo-Yo, who hasn't quite figured out his owner is dead. Can we find a way to get Yo-Yo to help solve the murder without breaking his poor doggie heart?
