Carrie Kennersly, a veterinary technician, has become known for offering healthy and popular dog treats at the clinic where she works. When the local bakery's owner moves away, Carrie jumps at the chance to convert it into the Barkery, a shop to make and sell her canine delights.

But Myra Ethman, co-owner of another pet product store, hates the new competition. At the Barkery's opening party, she badmouths Carrie’s homemade dog biscuits, insisting she'll find a way to shut the place down. So when Myra is found dead with a Barkery biscuit beside her, Carrie must prove she didn't do it before she's collared for murder.
