Doctor Kathryn Primm started Applebrook Animal Hospital in Ooltewah in 1998. In June of 2013 her book Tennessee Tails: Pets and Their People was published, chronicling heartfelt blog stories about her clients' pets as well as her own.

"Exploring the relationships that we, as human beings, have with our pets and how they make us a little bit better, a little more human," says Primm.

She wrote the book purely for the enjoyment, aiming to entertain. But some readers, Primm says, have gotten much more out of it.

"It made them feel like they wanted to be more responsible pet owners or they wanted to appreciate pets more," explains Primm.

But her experience with the Pet Placement Center in Chattanooga took the goal of the book down a different path after heavy spring rains damaged the shelter.

"They posted something about some flooding [on Facebook] and they were needing people to foster animals so they could get them out. So they could fix it up. So I thought they really need money. I wanted to help," recalls Primm.

She announced she would donate half the proceeds from first-year book sales to the shelter, the other half to the Humane Educational Society. Pet Placement Center board member and volunteer Linda Boyd was pleasantly surprised.

"Oh, we were so grateful," says Boyd. "We couldn't believe that she would be so generous to do that. Plus, it's such a wonderful book."

The Pet Placement Center, like many shelters, relies solely on donations and fund raising. So every dollar counts.

"It goes to house, to feed, to medicate all the pets that we take in here," explains Boyd.

Potentially 20 dogs and 60 cats can reside there all at one time. While Primm is pleased with the book, sales dollars have only gone to offset publishing costs. Until Primm turns a profit, the shelters won't see a dime.

"I really do want to get the word out about the book because it's important to me to be able to give them a big donation," Primm emphasizes.

The book costs just $8.99 and can be purchased at the following places: Applebrook Animal Hospital, on your Kindle, at Barnes & Noble bookstores, and on Amazon where it received a five star review. Primm adds that even if you're not an avid reader to please donate to local shelters whenever you can.
