I use a squirt bottle and squirt it right into the dogs mouth. I used to carry a small bowl and found you still waste water because you let the dog drink unitl it is satisfied , which leaves water in the bottom of the bowl. Although I used the water by pour it on the dogs back to help cool him off.
Same here. Squirt bottles work real well.
I also have a garden sprayer in the rig. If it's hot, I'll spray him down before we go out for a hunt, and spray him down again when we get back. He also likes to drink from the sprayer nozzle. Goofy dog.
