🐾 FIDO Score Calculator

Estimate your pet’s housing-related risk profile based on key factors. This tool provides an unofficial estimate based on the public FIDO Score™ concept by PetScreening.


Enter the age of your pet in years. Puppies and senior pets may have different risk profiles.


Weight can be a factor in potential property damage. Enter weight in pounds.


Documented vaccinations reduce health-related risks.


Past behavior is a strong indicator of future risk.


Some property managers perceive certain breeds as higher risk, regardless of individual temperament.

What is a FIDO Score?

The FIDO Score is a proprietary risk assessment tool developed by PetScreening.com to help landlords and property managers evaluate the potential housing-related risk of a household pet. Unlike a blanket policy that might charge all pet owners the same fee or restrict certain breeds, the FIDO Score provides a more nuanced, data-driven approach. It generates a score, typically from 0 to 5 “Paws,” where a higher score indicates a lower risk. This allows for a tiered system of pet fees, where owners of lower-risk pets might pay less than owners of higher-risk pets.

This FIDO score calculator is an educational tool designed to give pet owners an *estimate* of where their pet might land on this scale. It considers factors known to influence the score, such as the pet’s behavioral history, age, weight, and vaccination status. Understanding these factors can help you be a more responsible pet owner and potentially save money on pet rent. For an official score, you must use the PetScreening service.

FIDO Score Formula and Explanation

While the exact, proprietary algorithm for the FIDO Score is not public, it is based on a weighted combination of several key data points. Our calculator uses a simplified model to estimate the score. The core idea is to combine factors related to the pet’s individual characteristics and history.

Our estimated formula is:
Score = (Age Factor × Weight Factor × Vaccination Factor × Behavior Factor × Breed Factor) × 5

Each factor is assigned a value (typically between 0 and 1) based on the inputs provided. The product of these factors is then scaled to the 5-paw rating. You can learn more about related financial tools like a credit score estimator, which uses a similar concept of weighted factors.

Variable Explanations
Variable Meaning Unit Typical Range
Age Factor A multiplier representing the risk associated with a pet’s age. Unitless Multiplier 0.8 – 1.0 (Mature, non-senior pets are lowest risk)
Weight Factor A multiplier for risk associated with pet size. Unitless Multiplier 0.7 – 1.0 (Smaller pets are generally seen as lower risk)
Vaccination Factor A multiplier based on vaccination status and documentation. Unitless Multiplier 0.2 – 1.0 (Fully documented is lowest risk)
Behavior Factor The most significant multiplier, based on past incidents. Unitless Multiplier 0.1 – 1.0 (A clean history is lowest risk)
Breed Factor A multiplier reflecting common industry perceptions of breed risk. Unitless Multiplier 0.6 – 1.0 (Low-risk breeds score higher)

Practical Examples

Example 1: The Ideal Tenant Pet

A 4-year-old, 15lb Bichon Frise with full, documented vaccinations and no history of behavioral issues.

  • Inputs: Age=4, Weight=15, Vaccinations=Documented, Behavior=None, Breed=Low-Risk
  • Calculation: Factors would all be high (close to 1.0).
  • Result: An estimated 5 Paw FIDO Score. This pet would likely qualify for the lowest pet rent in a tiered system.

Example 2: The Higher-Risk Profile

A 1-year-old, 80lb Rottweiler that is not fully vaccinated and has a reported incident of chewing a door frame.

  • Inputs: Age=1, Weight=80, Vaccinations=Incomplete, Behavior=Minor Damage, Breed=Often Restricted
  • Calculation: The age (puppy), weight, vaccination, behavior, and breed factors would all be lower.
  • Result: An estimated 1 or 2 Paw FIDO Score. This profile represents a higher risk, likely resulting in a higher pet fee or deposit. This shows the importance of improving key factors where possible.

How to Use This FIDO Score Calculator

  4. Select Behavioral History: Be honest about any past incidents of aggression or property damage.
  5. Select Breed Risk: Choose the category that best fits your pet’s breed. This is based on common insurance and property management restrictions.
  6. Review Your Score: The calculator will instantly provide an estimated FIDO score from 0 to 5 Paws and visualize it on the gauge.

Key Factors That Affect the FIDO Score

Behavioral History (Most Important)
A pet’s history of bites, aggression, or property damage is the single most significant factor. A clean record is crucial for a high score.
Vaccination and Health Records
Having complete, up-to-date, and documented vaccinations shows responsible ownership and reduces health-related risks for the community.
Breed Perception
Fair or not, many property managers have lists of “restricted breeds” (e.g., Pit Bulls, Rottweilers). While an individual dog may be gentle, the breed itself can lower the score in this system.
Age of Pet
Very young puppies (potential for house-training accidents and chewing) and very old senior pets (potential for health issues) can sometimes be viewed as slightly higher risk than a mature adult pet.
Weight and Size
Larger and heavier pets are often perceived as having the potential to cause more significant property damage than smaller pets.
Owner’s Legal Attestation
In the official PetScreening process, owners must legally attest that the information provided is true. Honesty is a key component of the process.

Frequently Asked Questions (FAQ)

Is this an official FIDO Score?
No, this is a free, educational tool that provides an *estimate* based on the publicly understood factors. For an official score to provide a landlord, you must use PetScreening.com.
Why does breed matter if my dog is friendly?
The FIDO score is designed for property managers, who often must adhere to insurance policies that restrict certain breeds. The score reflects this industry reality, even if it doesn’t reflect an individual pet’s temperament.
Can I improve my pet’s FIDO Score?
Yes. The best ways are to maintain a clean behavioral record, keep vaccinations fully documented, and provide training. For puppies, the score can naturally improve as they mature and complete house training.
Is a 0 Paw score possible?
Yes. A history of a severe incident, like a bite, would likely result in a very low or zero-paw score, indicating an unacceptable risk for most rental situations.
Does my credit score affect my pet’s FIDO Score?
No, the FIDO score is entirely separate and is based only on household pet-related data, not the owner’s financial history. However, landlords will check both.
What is a ‘good’ FIDO Score?
A score of 3, 4, or 5 Paws is generally considered good to excellent, representing an acceptable or low risk to the property manager.
Do cats get a FIDO Score?
Yes, the PetScreening service and its FIDO score apply to all common household pets, including cats, not just dogs.
Why did you create a FIDO score calculator?
We believe in empowering pet owners with information. By understanding the factors that landlords care about, you can be a better-prepared and more responsible tenant.
