Let’s say you wanted to take your dog out on Union Street one day after work. So first, you pick her up where you left her that morning. Moulin Pooch is a “dog boutique and villa.” It would be nice to stick around for “Yappy Hour,” but she’s been there all day, so how about a change of scenery? At Pet Grooming Headquarters, a tiny shop a few blocks away, your dog can get a bath, a haircut, and a nail trim. Then, all fluffed up, it’s time for a treat. Le Marcel Dog Bakery, has 60 different treats for dogs and even birthday cakes.
