It's not the idea per se thats bad. There are a number of stories on YC which point to this problem: Most ideas are nothing without execution. (most recent: http://news.ycombinator.com/item?id=237096 )
Hell, I was in LA last week and saw a gourmet bakery for pets. No joke. They seemed to be doing brisk business. Several customers went in with their pets in the time it took me to drive by.
Apparently there exists a similar place in Tokyo. I remember watching a TV show where they rented a dog and took it there to eat. Apparently the humans and dogs could eat the same food.
Edit: Ah yes, Hello!Morning episode #331 and #332.
Mud Bay Granary isn't exactly a bakery, but it does nothing but sell expensive, organic, gourmet pet food. It's been in Seattle for years, and there are at least a half-dozen stores.
Sure - dog food is not an area I ever felt much like getting involved with. But for some aspiring mom in the suburbs it might be just the thing. A lot of people love their animals more than their fellow humans, so the money would definitely be there.
In fact TV advertisement for dog food is already going the gourmet route, which is disgusting. I remember an ad where the icky meat heap was decorated with a thyme leaf.
