Look into Dog Gone Safe.
Maddie’s Pet Forum
Maddie’s Pet Forum was developed to increase collaboration in the animal welfare industry and support pet caregivers all in the name of lifesaving. Shelter and rescue organization professionals and volunteers can communicate, collaborate, ask questions, and share expertise publicly in the forum and also privately within communities and groups created in the forum.
Offer low-cost dog training classes to dog adopters to help boost retention/prevent shelter return.
I wish we could afford a program to help owners (particularly of adopted dogs) afford behavioral intervention.
