Step-by-Step Guide to Using the Dog Age & Care Calculator

Step 1: Input Dog’s Age

Begin by locating the field labeled Dog’s Age (Years). Enter the age of your dog in years using this field. Ensure that the age is a numerical value between 0 and 30, as the calculator accepts age within this range only. You can adjust the age in increments of 0.1 for precision.

Step 2: Input Dog’s Weight

Move to the next field labeled Dog’s Weight (kg). Here, you should enter your dog’s weight in kilograms. Valid entries range from 0.5 kg to 100 kg. Like the age input, weight can be specified in increments of 0.1 kg to ensure accuracy.

Step 3: Select Dog Size

Next, select your dog’s size from the drop-down menu under the Dog Size field. The options available are Tiny (up to 5kg), Small (5-10kg), Medium (10-25kg), Large (25-45kg), and Giant (45kg+). This input helps personalize the calculations to accommodate size-specific requirements.

Step 4: Choose Activity Level

Proceed to selecting the appropriate Activity Level for your dog. Options range from Inactive/Senior (value 1.2) to Very Active/Working Dog (value 1.8). Choosing the correct activity level is crucial as it influences calorie, water, and exercise recommendations.

Step 5: Viewing the Results

  • Human Age Equivalent: Once all inputs are correctly entered, the calculator will compute the Human Age Equivalent using the formula: 16 * log(dogAge) + 31. This is displayed in years, rounded to zero decimal places.
  • Daily Caloric Needs: The calculator determines the daily caloric requirement with the formula: 70 * pow(dogWeight, 0.75) * activityLevel, displayed in kcal/day.
  • Daily Water Intake: Calculated as dogWeight * 0.065, providing the recommended water intake in liters per day to two decimal places.
  • Daily Food Amount: The amount of food necessary per day is derived by dividing daily calories by 350, expressed in cups/day to two decimal places.
  • Recommended Daily Exercise: Exercise time is calculated with the formula: activityLevel * 20, yielding the recommended minutes of exercise per day, with no decimal places.

Ensure all input fields are filled out accurately to obtain precise results tailored to your dog’s specific needs.
