At high temperatures, dogs lose a lot of fluid, especially when they move a lot. Sweating is a secondary process in dogs; sweat glands are only present in the balls of the paws. Respiration is another matter. Dogs release a lot of fluid into the air via panting and breathing to produce cooling via evaporation. Unnoticed by humans, the dog invests a lot of fluid in the regulation of its body temperature. A dog weighing around 20 kilograms already consumes around a quarter litre of water by breathing at low activity levels and at moderate temperatures. With heat or exertion, consumption increases drastically and can be up to two litres in high-performance sports. It is not surprising when the dog gets thirsty on the go. However, water from puddles or stagnant pools often causes digestive problems and may contain pathogens. That’s why a dog water bottle is the ideal solution when you’re out and about.
