That wasn't a dog, that was a horse. Why would he need a dog as a companion at the restaurant when he had his wife there. People are getting carried away with this.
Yeah I know right, the guy must have big emotional problems that requires a dog-horse at a restaurant, and yes I also think this is redunkulous, if I had that much a OCD, DYS, GRT, HFE, KLB, MGO.............problem I'd stay home.
