Gaits of Heaven — Susan Conant

Poor Dolfo. It wasn't the golden Aussie huskapoo's fault he wasn't housebroken. Blame it on Ted and Eumie, the overmedicated, overanalyzed, superdysfunctional New Age couple who couldn't bring themselves to restrain their dog's free spirit with collars, leashes, or obedience training. That's up to dog trainer Holly Winter. And now Holly has another task: finding Eumie's killer. Sure, the doctors said it was an accidental overdose of mixed meds, but this weird family has too many dirty secrets not to count murder among them...
