Review on Portable Pet Feeding Dish With Carabiners: 2-Pack Collapsible Dog Bowls For Traveling, Camping And Walks by Melisa Byers

These collapse/open -- popping in/out -- fast and easy. I like the carabiner for easy attachment to a water bottle, backpack, or leash handle. These were smaller than I imagined, but that still works for my medium breed dog (40lb female husky). I need to refill water often but that ensures she always has fresh, clean water to drink. Less to get dirty (especially at campsite) and tip over from a human or canine bumping into it. Ideally a bigger bowl would be better for my dog, but my family plans on getting a smaller breed some day. I have used larger collapsible bowls to take along on day-hikes, but my dog only drinks a small amount of time, so I ended up wasting water that way. This small size allows me to pour enough that she will drink during rest-stops.
