Small Stinky Treasures bags
These bags are the perfect walking companion when you take the pup for a walk. It has a pocket for rolls of bags (or even loose ones), a pocket closed with velcro for keys/money and a lined main pocket for the filled stinky bag to go in to, so you're not stuck carrying a decidedly stinky thing all over the place.
2 sizes are available. Small, fits al small breeds up to I'd say beagle. Large will go up to great dane. I CAN make extra large if needed, if you walk a moose, or many dogs.
