Rodzinski, "Sand in My Shoes" was kind of a standard for Bobby Short. He had a few versions, I believe, on a couple of albums.
DakotaCelt, Tewkesbury is the dog. He's a mutt but probably has a good dose of schnauzer in him as well as either Yorkie or Silky or some kind of terrier. I have no idea where is white plume of a tail comes from.
Mosby is the Cat, alternately known as The Grey Ghost. You're probably far too young to remember the TV show about Civil War Confederate Raider, John Mosby, who was also known as the Grey Ghost, played by Tod Andrews. There was a theme song that went: "Grey Ghost is what they called him, John Mosby was his name."
The Cat, before he was named, was dubbed the Grey Ghost by me for his habit of stealthy, startling appearances and so Mosby folllowed as a moniker. "Grey Ghost is what they called him, Cat Mosby was his name!" "Cat Mosby" is what they actually had on his records at my old vet and what the vet always called him. He usually called around here Mo, Moto, Mighty Mo. Or "you ornery bugger". The dog is Tewkes, Tewke, Tewker. Or just, "you shit-brained woogie."
