Self pouring pet water bottleThis is absolutely the handiest thing on walks with our collie! It's a water bottle, that has a top that flips into a bowl, then fills with water for your dog to drink, any leftovers can be pulled back into the bottle, or thrown.This is a good size at roughly 19cm tall and 8cm wide. You have a lanyard and a carabiner clip. There is a switch to unlock, so once you've unlocked it, you give the bottle a squeeze and it fills up the bowl, lock it before you let go to hold the water up there while the dog drinks. When you're ready you can throw it away, or unlock the switch and the bottle will suck the majority of the water back in.I think this is a brilliant invention and I would recommend it for any dog lover/dog walker.
