GoPaw offers small, medium, and large cups in blue, green, and orange, with soft non-toxic silicone bristles and a simple add-water, move-up-and-down, and towel-dry routine. Nine currently available variants make it easy to match approximate dog size and color preference, and the compact cup can stay in a car. Its size labels are based on body weight rather than published paw-opening measurements, so fit is less precise than the top-ranked cups.
