Daily Water Intake
Expert Tip
Dogs eating 100% dry kibble need to drink significantly more fresh water. Dogs eating wet food or raw BARF diets cover up to 70% of their hydration requirements directly through their meals.
Calculation Methodology & Details
Formula
A dog requires about 50 to 60 mL of water per kilogram of body weight (roughly 1 fl oz per pound). This value increases by 50% for high activity or heat, and decreases by up to 30% if the diet contains high moisture (wet food).

How to Determine Water Needs: Step-by-Step
Find appropriate hydration goals using these steps:
Determine Weight in kg
Obtain weight. Convert lbs to kg by dividing by 2.2.
Calculate Base Requirement
Multiply the kg weight by 55 mL to get the basic volume.
Apply Environmental Factors
Add 50% extra for active dogs or hot seasons, and subtract moisture credit if feeding canned or raw diets.
