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

๐Ÿ“

Formula

Base Water Intake (mL) = Dog Weight (kg) × 55 mL Adjusted Intake = Base × Activity Factor × Diet Factor

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:

1

Determine Weight in kg

Obtain weight. Convert lbs to kg by dividing by 2.2.

2

Calculate Base Requirement

Multiply the kg weight by 55 mL to get the basic volume.

3

Apply Environmental Factors

Add 50% extra for active dogs or hot seasons, and subtract moisture credit if feeding canned or raw diets.
