Dog carriers, like baby strollers, have become luxury items. At the top of the line, the doggy equivalent of the must-have Bugaboo stroller is Louis Vuitton’s Sac Chien carrier, which at $1,300 probably costs even more than your furry friend. Now, without suggesting that he or she isn’t worth the very best, let’s get a handle on what’s really going on in that bag—sleeping, snacking, and perhaps a little “treat.” Why risk it? Just in time for warm weather, there’s Baggallini’s Bark ’n Beach Tote; $50 at Fetch (43 Greenwich Avenue; 212-352-8591). It’s lightweight, comes in four colors, comfortably holds dogs up to fifteen pounds, and has a sporty look for the modern pooch-on-the-go.
