Soba is one of two sisters (the other is Noodle) who came to Rolling Dog Ranch from a humane society in Iowa -- both with a neurological disorder known as cerebellar hypoplasia, which makes them wobble, flop, flail and fall.

But both seem very happy dogs.

Steve said Soba's mom, when pregnant, got distemper. As a result, some of her pups were born with the disorder. Two others were born totally paralyzed and one was unaffected.

Noodles is rarely shown to visitors at the ranch because some guests get upset by how much she falls.

Soba and Noodle, meanwhile, take their condition in stride. ”They have no idea anything is wrong with them," Smith said. "They just live their lives and are perfectly happy”

Soba, the more coordinated of the two Collie mixes, takes a while to get where she's going. At times, she seems to be going in all different directions as she walks, as if each leg has a mind of its own.

Sometimes all four will be flailing, but she gets nowhere. Other times, they make contact and propel her to her destination.

But neither seems frustrated by their handicap, or by how long it takes them to get where they want to go, as you can see in this Rolling Dog Ranch video (below) of Soba:
