Apologies for the hi-jack but I saw a real Pooch Cafe in Vancouver last year.
Very bizarre. They had a small shop which they had turned into said cafe. Small tables and stools for the customers, a deli counter serving homemade meat based treats with vegan and veggie alternatives also available. I only had a short time to talk with the proprietor and she was lovely but ever so slightly bonkers. I think they'd been trading for nearly 3 years.
