My super sweet dog gets separation anxiety when I leave her alone with her doggie siblings. But many strangers in public terrify her also. Well, with the G-Train Dog Carrier, she can stay hidden when she thinks a stranger looks suspect, and pop out and look adorable when she thinks a stranger looks friendly. She’s 15 pounds, so the 25-pound limit of the bag is perfect for allowing her this option. Also, the bag is great quality all around!
