Bite the Biscuit — Linda O. Johnston

Veterinary technician Carrie Kennersly has become known for offering healthy dog treats at the clinic where she works. So when the owner of the local bakery moves away, Carrie jumps at the chance to buy the business and convert half of it into the Barkery, a shop where she can 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. 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.
