Story first: My mom (may she R.I.P.) needed a little coaxing but she found an older Pom and I think it was LOVE at first sight. We didn't know much about the little guy and mom had been living alone for a couple of years. My cat had passed away a few years before and she had said, "No More! I just can't take the loss of another pet."
I knew she was lonely without a pet and studies show pets are good for us...and it would be good for her.
So, when her apartment complex opened up to small dogs (it had been cats only) we talked about it and she found Bubba-Lou a beautiful blonde Pom. My sister is a groomer so the grooming expense wasn't an issue. Bubba got mom out of the house and although mom was a social butterfly, dogs add just a little more.
Mom and Bubba had a few good years together, I am glad to say. She spoiled him rotten (lol). When she would travel, he would come here to visit with her grand-dogs and did just fine. (She
LOVED my Am Staff and Cattle dog but I didn't ask her to "handle" them, she also bragged on her grand-dog (my Am Staff) to EVERYONE. Ha!)
Point being: I think if it sold as they are spayed/neutered we need foster care so we can find forever homes, you would be surprised how many would open their homes to it. If they are not on a low "fixed" income, they might be willing to buy the food. Vetting might be another issue but cross that bridge when you get to it. Each person and their needs will be a little different. As will be what dogs and breeds they will want to handle.
Or they are rescues and need homes, they aren't puppies with high energy or powerful breeds, seniors (at least some) know what it's like to be on that side of the deal (you aren't the young one on the block...someone else has come in and taken over...) and can relate. You would be surprised who would open their homes and hearts. You can sell these rescues as the ones that get passed over by the young families that want puppies or young dogs with lots of energy. These are the dogs that are happy finding a place in your heart and in your home.
I would also take a couple of dogs with me. Maybe one with medium and one older low energy? I also liked the bandana idea
