Carrying cold water on walks is super important, and in hot weather it’s crucial and could be the difference between your dog staying safe or developing heatstroke. This water bottle works well for me as its large capacity makes it suitable for multiple dogs - I use this bottle for 1hour group walks, and will take my 2ltr bottle on 2-hour walks if it’s especially warm. It’s important that the bottle is insulated, as drinking cool water is one of the main ways in which dogs can cool themselves, so it’s no use if the water is able to heat up to ambient temperature whilst you’re out and about! The detachable bowl on the bottom is really useful, and the handle makes it easy to carry. For anyone with one or two dogs this may be a little large for the every day, but it’s great for summer and especially great for all-day adventures, eg. day trips to the beach!
