I have a Labrador whom is almost 6 months old.  He loved the moving water of course and true to lab wanted to play in it.  The play didn't last long as he soon licked the water from the spout.  When he was serious about wanting larger amounts of water he went for the corners and his snout barely had enough room clearly as he gets older this may be an issue. The bowl does hold the 70 ounces and the filter is doing a great job of filtering the dirt and junk that my lab gets in.  This fountain has many components to it so cleaning it to get the doggie slime/slobber is a bigger task than a regular bowl.  Overall, I am going to use this fountain upstairs where it doesn't get much use rather than an everyday bowl. [This review was collected as part of a promotion.]
