Fortunately, the shelter director knew the dog because he had been coming there for years and she knew how good the dog was. And she also felt that the community owed the dog more than he had been provided. She sent out emails that eventually made their way to me.
My weekend was free, so Saturday I made the three hour drive to pick up Jasso. He is sweet and friendly. He rode beautifully in the car. I had brought Maya along, but I left her in the crate and gave Jasso the space behind the seats. He laid down for the long drive home, getting up only occasionally to change positions. The shelter had kindly given him a bath that morning, but he still smelled from the yeast infection on his skin. I hated to bathe him again right when I got him home, but he needed a medicated bath as soon as possible so that's what we did. He was good about it and even let me trim a few of his toenails while we were waiting for the shampoo to set on his skin.
He ate, and I gave him a small portion of Satin Balls as a snack later in the day. I put him in a crate with a big comforter, which I warmed up in the dryer before bedtime last night. He can manage the few steps required to get into and out of the house, but I don't think he could get upstairs on his own so he took one of the crates in the kitchen. We took some outdoor photos after breakfast this morning after which he headed right back to his comfortable bed in his crate. This household isn't ideal for an old dog in his condition, but we can cope. I will get him to a vet (former owner never did), and we'll work on making him as healthy and as comfortable as possible. I hope to find him an adopter who can and will provide him the retirement home he deserves.
