I can't answer on behalf of LS. But I can offer some thoughts on the issue. For any adoption to be successful, it has to meet the needs of the individual dog as well as the adopting family. Some dogs have very special needs to help them blossom into the dog they were born to be.
Many people who may turn to rescue for their next pet only want a young, healthy, pretty, trained dog and do not realize the love and patience that might be required by a rescue. Unfortunately, also, many people don't look past a dog's age or physical limitations and see the love that the dog has to give. Older dogs are wonderful and give so much back for so little input. But many people just skip over older dogs or ones with medical conditions.
So please think about adopting an older dog who really needs a home of their own. In the meantime, the dogs are safe in a loving foster home while they wait for the right fit of a forever home. I love the old timers who like me just want a hug and a warm bed and someone to love in their golden years. If you can't adopt one, I hope you will think about a small donation to help with their medical needs.
