A dog can empty a small water bowl surprisingly quickly. The 4.1 litre Viva gives them a roomier supply, with a gentle bubbling flow rather than a falling stream.

Quiet water flow, useful reminders

A submersible pump circulates the water through Ion-X and foam filters. The low-water LED is a handy reminder to top up, although it is still worth checking the bowl as part of your daily routine.

• 4.1 litre capacity for dogs
• Soft bubbling water flow
• Two-stage filtration
• Simple design that comes apart for cleaning

The plastic-tray fountain comes with an Ion-X filter, foam filter, USB power cable and quick-start guide. Follow the guide when washing the removable parts and cleaning the pump. This is the larger Viva model, rather than the 1.8 litre version.
