Saw this and immediately added to cart! I will go ahead and add, though, I really wanted the black backpack, but I couldn't figure out any differences except the color, and I didn't think the color was worth a small price increase. This bag is great, though! Plenty of room for my 23lb dogs supplies when we travel. Has a poop bag holder on the very front, as pictured. On the exterior back it has a small zipper pocket where the straps are. On the exterior sides there are two water bottle holders, one on the left and right. Then, still on the exterior, there is the front zipper pocket (where the poop bag goes) that is very roomy! Inside, there is the main compartment, and then a zippered pocket on the front interior backpack zip part (does that make sense? Lol), and a little sleeve pocket on the back. I think if you have a medium/small dog you can definitely pack the travel essentials for a weekend trip. With a big dog this is probably great for a day trip, or just holding the leash, treats, etc. Definitely recommend!
