Doesn't make sense to me, but it made me laugh, so that has to be worth something. I didn't Google it, but it seems like a tough sell. I assume there are a handful of businesses with that name, but they still don't need the name, I wouldn't think. They could use BulldogCoffee.com, BulldogCoffeeHouse.com or something similar. The odds of you getting lucky without putting in a good bit of effort are very low. Even with hard work, there is little chance for a nice sale. This is the type of name that can cost you a lot of your time if you are not careful.
I had a name called VarietyMotors.com a while back. Not only was there a site at VarietyMotors.net, but there was also one at VarietyMotors.us. I wasted a lot of time emailing these people every 6 months or so. Now, I almost sold it a few times, but in the end I really couldn't even give it away. It baffled me then, and still does in a way. The Bulldog Coffee name has far worse prospects, I would think. Of course, sometimes you strike with these types of names, but the key is to have a bunch of them in various categories, since there is no guarantee for any of them to sell. You never are quite sure which ones you will connect with.
