Cupped hands and a folded poo bag are the two worst ways to water a dog, and this bottle exists to replace both. The lid opens out into a shallow trough, one button pushes water into it, and whatever your pet does not finish tips back into the bottle when you close it again, so there is no puddle on the pavement and nothing damp in the bottom of your bag.

The whole thing runs from a single button, which means the lead stays in your other hand throughout. Two capacities are made, 350ml and 500ml, in pink or blue. The smaller one is the better shape for a coat pocket; the larger is the one to take if you are out for a couple of hours in warm weather, or driving somewhere with the dog in the back.

• Flip-up drinking trough moulded into the lid
• One-button dispensing, usable one-handed
• Unused water tips back into the bottle
• Choice of 350ml or 500ml capacity
• Available in pink or blue

On capacity. 350ml is a couple of good drinks for a terrier and not much at all for a labrador on a summer walk. If you have a big dog, or you walk somewhere with no tap and no stream, take the 500ml and fill it before you set off rather than halfway round.

Who it's for: Anyone walking, driving or travelling with a pet who needs water on the way and has nowhere sensible to put a bowl.
