Pet Over Population Prevention or POPP could really use a helping hand right about now. Since POPP is not a shelter, they need foster homes. Fostering is a great idea if you think you want another pet but aren't sure. Bringing in a foster dog is a good way to see if an additional dog is a good match for you. POPP even provides the food, toys and crates for your foster dog. Once your foster dog finds a forever home, you can get another if you choose to, or not.
