Ido score pet screening is reshaping how landlords, tenants, and property managers assess risk and set pet policies in U.S. rentals. Whether you are a pet owner hoping for approval, or a property professional seeking reliable risk metrics, understanding the IDO (often called FIDO) Score is critical for making smart, fast decisions. Here’s exactly how it works, why it matters, realistic limitations, and expert strategies to use it to your advantage.
Key Takeaways
- The IDO (FIDO) Score uses 35+ pet and owner data points to rate risk on a 0 paw to 5 paw scale—lower scores mean higher rental risk.
- Landlords get faster, centralized results, but the screening process remains partly opaque and can feel rigid to pet owners.
- There are actionable steps renters can use to improve or prepare for screening, but appeal options and score improvement strategies are rarely publicized.
The Core Concept: What is IDO Score Pet Screening and Why it Matters
The IDO Score—often referred to as the “FIDO Score” by PetScreening—is a numeric system designed to help property owners and managers evaluate the risk pets bring to rental housing. Pets and their owners are scored from 0 paw (highest risk) to 5 paw (lowest risk) based on 35+ data points including breed, age, size, behavioral history, and vaccination records. The goal is twofold: protect properties and standardize pet screening across rentals.
For landlords and property managers, this tool streamlines approvals and pricing, and eliminates paperwork headaches. For tenants and pet owners, it clarifies requirements, but can feel daunting due to sometimes opaque or proprietary scoring details.

Why does it matter? Rising rental demand and shifting pet policies have made consistent, fast, and compliant pet screening essential. Landlords use the IDO/FIDO Score to set pet fees and approval policies, while renters rely on it for transparency and fair evaluation. Its adoption marks a move away from blanket bans and arbitrary rules, unlocking more pet-friendly rentals while addressing risk up front.

Step-by-Step Guide: How the IDO (FIDO) Score Actually Works
PetScreening created the FIDO Score to give landlords and renters a frictionless but detailed risk assessment in under an hour. While some proprietary details are kept private, here is exactly how the screening works and what you can do to optimize outcomes:
- 1. Pet Profile Submission: Pet owners fill out an online profile for each pet. This includes the animal’s name, age, breed, weight, sex, color, photos, microchip, spay/neuter status, and recent vaccination documents (source).
- 2. Attestations & Behavioral Disclosure: Owners must legally affirm over 21 detailed statements—covering bite history, vaccination status, aggression issues, care knowledge, and unique behavior details (source).
- 3. Automated Data Review: The system combines 35+ data points, including any community-specific breed/weight restrictions, into a risk scoring model. The exact weighting or mathematical formula is not public and may adjust for each pet type (source).
- 4. FIDO/IDO Score Generation: The pet receives a score between 0 paw and 5 paw. Lower scores signal higher risk based on provided info, breed, vaccination status, and self-reported behavior.
- 5. Risk-Based Recommendations: Property managers see the score, pet details, and suggested tiered pricing for pet rent. Example: 0 paw $35/month, 5 paw $20/month (source).
- 6. Record Storage & Compliance: Documents and attestations are stored securely and can help ensure FHAct and HUD compliance for service animal requests, though public details on appeals, privacy, or audits are limited.
Additional actionable tips:
- Be honest on all attestations—false info or spotted fraud can result in immediate denial and even future rental blacklisting. PetScreening identifies up to 60% of accommodation requests as insufficient or fraudulent.
- Highlight recent training certification or behavioral progress—in some cases, extra detail here helps with marginal scores, especially for “at risk” breeds or those with past incidents.
- If you fail with one pet, consider screening a different pet or reapplying after resolving flagged behavioral or documentation gaps.
- Reach out to the property manager to clarify what FIDO Score levels are approved for their property, since specific cutoffs are private or may vary by landlord.

Advanced Analysis & Common Pitfalls
While the promise of the IDO/FIDO Score is objectivity, the system is not without its problems, lack of transparency, or occasional unintended consequences. Here’s what renters and property managers need to know before relying on—or challenging—the process:
Common Pitfalls & Problems
- Opaque Criteria & Weighting: Neither landlords nor tenants can see the exact risk weights, algorithm, or why pets receive a specific score—leaving appeals or corrections extremely limited (source).
- No Automatic Appeal Mechanism: There is no published, easy appeal or dispute process for rejected or low-scoring applications. If you dispute a result, your only path is to work directly with the landlord.
- Limited Path To Score Improvement: The system offers little guidance on how to “raise” your FIDO Score apart from submitting more documentation. Owners with previous behavioral incidents rarely see specific improvement suggestions.
- Data Privacy Largely Unclear: Although information is stored securely, little public info is available regarding privacy standards, audit trails, or data handling for denied applicants.
- Landlord Usage Is Inconsistent: Not all landlords use the same FIDO Score approval limits. Some may allow scores as low as 2 paw, while others only accept 4-5 paw. Criteria often change without warning or transparency.
- No Independent Effectiveness Validation: There is scant evidence showing whether FIDO Scores are more predictive of pet-related rental damage compared to traditional referencing, interviews, or alternative screening services.
Here is how score-based pricing might affect monthly costs (per PetScreening data):
| FIDO Score | Sample Monthly Pet Rent |
|---|---|
| 0 paw | $35 |
| 1 paw | $40 |
| 2 paw | $25 |
| 3 paw | $30 |
| 4 paw | $25 |
| 5 paw | $20 |

Gaps & Underaddressed Subtopics
- No explicit path to improving scores—owners with previous issues get no clear advice on repairs, training, or demonstrating responsible ownership.
- Rarely-published minimum passing scores for individual buildings or management companies; renters must always ask managers for clarifications.
- No clear regional or property-type variations—score acceptance seems to stay the same for all areas and home types.
- Nearly all data is U.S.-centric; international pet renters find the FIDO system does not apply.

Conclusion
The IDO Score pet screening system brings speed and standardization to pet risk assessment in U.S. rentals, but its math remains a black box. Landlords benefit from time savings, and many responsible pet owners gain easier access to more rentals. Still, gaps exist in score improvement transparency, published appeal rights, and unbiased validation.

No. Each landlord or property manager sets their own minimum passing scores for pets. Some may allow pets with lower scores, while others only accept high-scoring pets. Always clarify requirements before applying.
How accurate is the IDO/FIDO Score at predicting pet risk?
Public validation is limited. While the system is widely adopted, there is little independent evidence showing it outperforms traditional interviews or alternative screening tools in reducing pet-related rental issues.
