This looks like a neat gadget for those dogs who have trouble drinking in the field. Fortunately, my dog drinks from every mud puddles she sees. She especially likes the deep sunken tires ruts that are filled with stagnate water. Then she will go down and wade in the creek and drink from there. One thing you should all remember about giving a dog drinking water in the field..... you should sprinkle their nose with water. This cleans their nose of dust and pollen and keeps their nose from drying out which will help them to pick up scent better. Thanks for the tip, Chuck.
