Our Mission Nashville Humane Association is committed to finding responsible homes, controlling pet overpopulation and promoting the humane treatment of animals. Adoption Policy The adoption process at NHA is friendly, educational and rewarding! Animals come to us looking for a forever home, and we make certain to give them their best shot. All animals in our Adoption Program, while at NHA, receive spay/neuter surgery, vaccinations, and veterinary treatment. And of course, lots of love!
