From the site:
Unlike a shelter or humane society, our dogs are not in one central location, but spread throughout many foster homes across the state. We realize that this makes it difficult to 'come meet our dogs,' but we believe the one-on-one care our dachshunds receive is well worth the inconvenience.
Most CTDR dogs come from Texas animal shelters where they are in danger of being euthanized. We also accept animals from the public if space is available in an appropriate foster home. Some of our dachshunds have had a good life, but have fallen on hard times because their master has passed away or because they've escaped their yard and become lost. But some of the dachshunds we take in have been abused, abandoned and neglected and require time and patience to bring them back to happy, healthy, loving pets.
