Promising review: "This worked great on my giant breed dog. I was able to wet all of him down with so little effort. It was easy to hang the wand on the suction cup when I didn't need it. With the full spray, there was enough water pressure to wet down the thick downy fur on his back end. I was able to carefully wet up under his legs and tummy using the narrow spray and reduced water pressure. One-handed operation was a little tricky at first, but I got it eventually. Best of all, the hose was long enough to reach his backside at the far end of the tub. I'm really surprised at how well it worked because my closets are stuffed with doggy gadgets and toys I thought would be awesome and then never used. Bottom line, if you're a doggy parent, this is a great investment that will make your doggy bathing life a lot easier. It could easily be used on my short-haired 10lb dog as well. I'm considering buying another to put outside for washing down my lab after her ocean swimming, woods tromping, mud puddle splashing adventures and for all those rainy-day muddy paws." –seastorm
