Rescue Me by Andrew Grey

Everybody needs to be rescued sometime.

Veterinarian Mitchell Brannigan gets off to a rocky start with his new neighbor when someone calls the town to complain about the noise. Mitchell runs a shelter for rescue dogs, and dogs bark. But when he goes to make peace, he meets Beau Pfister and his fussy baby daughter, Jessica… and starts to fall in love.
Beau moved out to the country to get away from his abusive ex-husband, but raising an infant alone, with no support network, is lonely and exhausting. The last thing he expects is a helping hand from the neighbor whose dogs he complained about.
Mitchell understands what it’s like to live in fear of your ex, and he’s determined to help Beau move on. But when an unseen menace threatens the shelter and Beau, it becomes apparent that he hasn’t dealt with his own demons.
With each other and a protective Chihuahua for support, Mitchell, Beau, and Jessica could make a perfect family. Mitchell won’t let anything happen to them.
But who’s going to rescue him?
