Yeah, flyball looks like it would be so much fun! Finn loves tennis balls, but, I've never asked him to jump over a hurdle. I don't think it's good for his hips this young. But, soon! I'm going to search online for ideas, and, I know a guy that is really handy and I'm sure if I bought the supplies and threw in a bottle of Crown Royal or something, he'd help me put everything together. I don't want or need anything fancy. Just practical and safe.
