NP Sandy, "ain't no thing" either way.
Too bad about the guard, but -- that photo just cracks me up. The guard actually seems somewhat "amused" by the results and the dog is just being a dog... "some nice play, now for some dinner and water and perhaps a good ball licking..." You can just picture the scene as a beserk (ie. joyfully playful) Barney reacts like you would expect of a bull in a china shop or a dog in a stuffed animal museum
