Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.
Daily water consumption varies quite a bit. Season of the year, workload, reproductive status, diet, and climate factor into the volume of water needed by a particular horse on a specific day. As a starting point, the average horse drinks between 5 and 10 gallons (19 and 38 liters) of water each day. The horse may need slightly less if it is grazing lush pasture because fresh grass contains a high percentage of liquid.
The table below shows daily water requirements for dogs of different weights. Weight (lbs.) Cups per Day 10 1.0 20 2.1 30 3.1 40 4.2 50 5.2 60 6.2 70 7.3 80 8.3 90 9.4 100 10.4 Once you have an idea of how much water a dog should be drinking each day, the next step is to monitor their actual water consumption.
