I would make a good therapy dog or just a good dog!

Colly is a two-year-old mutt with long, racing legs, a wiry coat, and a terrier face. She's a big dog. She understands basic commands. She's a sweet dog, a calm dog. She's wants to please. She was rescued from a shelter a year ago and already she needs another home. Her owner has been transported to a nursing home. She was the center of his attention. I'd like her to go to a good home. I hate to let her go myself, but she's just too big for my two little dogs.
