Volunteers play a vital role in our organization. Without their support, we would not be able to assist the number of animals who need help in our community.

Foster Opportunities

We are always looking for responsible foster homes to take in homeless or unwanted animals for a limited period of time. In general, that ranges from a few days to a few weeks. Foster homes may work with dogs - teaching manners, house-training, and other necessary life skills. Foster homes may also provide a safe, quiet place for nursing moms and growing puppies/kittens.  Foster volunteers not only save lives, but they also prepare pets for the best life possible.

Note! PACFA (The government agency which regulates animal welfare agencies in Colorado) now requires all foster homes to have routine inspections. Fosters will be inspected on an annual basis by an appointed shelter representative. Learn more.
