We travel with this bag. Convenient because we take take what we need for our mid size dog.We got this when our dog was a puppy and love it so much. A little bigger than I thought but fits a lot! Perfect for traveling!It is rather difficult to judge the size even when dimensions are given. This really surprised me. It is big. I can hold just about everything I need to travel with my pup. The food storage is large enough for a week's worth of food. The compartments will hold all her treats, toys, and vitamins and even some cleaning things to take along. I am very happy with this bag. It seems durable enough to hold everything. I haven't had it long enough to report on multiple uses and overall timeframe.For everything you get for this price, it’s amazing. This is the best deal I’ve seen on Amazon. Has a treat bag, a dog food bag, water and food bowl that collapsible, and a water bottle holder. There’s several organization places and slots and this bag is big enough to hold some personal items as well. I definitely made the right decision.I have been using this for almost 2 months with our puppy. It holds SO much more than I expected and is holding up very well. I love all the compartments/pockets it has as well! The water bottle holder on the side is a little tight (if you are using a reusable water bottle) but other than that, it is a lifesaver!a lot bigger than i expected so much roomWorks great and comes in handy. Took to the river with the babies (dogs). Everything fit in it for them.This product is amazing, everytime i travel i make sure i use it. It holds my dog and cat toys, their food, vaccine records and it comes with two free collapsible bowls.
