Water is the most important substance on the Earth for living creatures
Those of us interested in the prospect of life existing outside our planet are well aware that scientists assume that a remote planet MUST have (or have had) water on it to support life-forms.
Mammalian bodies consist of 70% + water, and most of this is intracellular. Animals (including humans) can survive the loss of most of their stored carbohydrate (as glycogen), most of their stored fat (as adipose tissue), and over 50% loss of body protein - but if they lose just 10% of body water they are seriously ill, and loss of 15% water can lead to death !
Owners must therefore ensure that their pets are provided with sufficient fresh, clean water and water should be available 24 hours a day, 365 days a year.
Water can be a source of infection for animals, so dirty, soiled water should be removed from the environment as soon as possible, and the supply replenished.
Human grade tap water is ideal for most pets and it should contain less than 5000ppm total dissolved solids (TDS). Water containing over 7000ppm total TDS is considered unacceptable for livestock and other animals . Salt water living creatures require highly specific water conditions. Hard water contains high concentrations of mineral components eg calcium, magnesium and other anions. Commercial mineral water packaged for human consumption should not be given to pets, except on the advice of a veterinarian, because some are very high in salt, calcium, magnesium and other minerals which could be contraindicated for your pet. For example, pets with hypertension or struvite urolithiasis should not be given water with high sodium or magnesium concentrations, respectively.
Water should not be provided to pets if it could be :
How much water do pets need ?
Water requirements depend upon :
Water loss from the body increases with :
There are three main sources of water for pets :
As a general rule dogs and cats require the same amount of water (ml/day) as they do calories (kcal/day) .
