Pet insurance can save you thousands of dollars in veterinary bills, but only if you choose the right plan. Many pet owners sign up without fully understanding coverage details, exclusions, or long-term costs. The result? Denied claims, unexpected out-of-pocket fees, or policies that don’t match their pet’s needs.

Use this guide to learn the most common mistakes pet owners make when buying pet insurance—and how to avoid them so your pet gets the best protection possible.

1. Don’t Wait Until Your Pet Is Older

One of the biggest mistakes is waiting until pets develop health issues or reach senior age. By then:

  • Policies cost significantly more
  • Many conditions are considered pre-existing
  • Some insurers won’t accept older pets
  • Coverage options become limited

The best time to buy pet insurance is when your pet is young and healthy.

2. Don’t Choose the Cheapest Policy Automatically

Low premiums are tempting, but cheaper plans often include:

  • High deductibles
  • Low annual limits
  • No coverage for hereditary conditions
  • Limited reimbursement percentages
  • Fewer diagnostic or treatment options

In many cases, the cheapest plan ends up costing more over time.

3. Don’t Overlook Deductible and Reimbursement Options

Pet insurance policies vary widely in how much they reimburse after a claim. Key decisions include:

  • Reimbursement percentage (usually 70%, 80%, or 90%)
  • Annual deductible (high vs. low)
  • Annual or per-condition limits

Choosing the wrong combination can significantly affect your actual out-of-pocket cost.

4. Don’t Ignore Pre-Existing Condition Rules

Pet insurance companies do not cover pre-existing conditions. Many owners don’t understand that conditions become “pre-existing” if:

  • Symptoms appeared before coverage
  • Vet records show early signs
  • The pet was diagnosed before enrollment

Not knowing these rules can lead to surprise claim denials.

5. Don’t Assume Wellness Care Is Automatically Included

Routine and preventive care—such as checkups, vaccines, dental cleanings, and flea medication—are usually not included in standard accident + illness policies.

You may need a separate wellness plan or rider to cover routine care.

6. Don’t Skip Reading the Illness and Accident Definitions

Not all policies define conditions the same way. Important distinctions include:

  • Acute vs. chronic illnesses
  • Congenital conditions
  • Breed-specific hereditary conditions
  • Bilateral conditions (ex: hip dysplasia)
  • Accidents vs. injuries

Some policies exclude or limit coverage for certain breeds entirely.

7. Don’t Forget to Check Waiting Periods

All pet insurance plans have waiting periods, including:

  • General waiting period (often 14 days)
  • Orthopedic or cruciate ligament waiting period (up to 6 months)
  • Illness waiting period

Accidents or illnesses that occur during these waiting periods are not covered.

8. Don’t Assume All Vets Accept All Pet Insurance

Pet insurance usually works on a reimbursement model, so you can visit any licensed vet. But some policies have:

  • Restrictions for specialists
  • Required pre-authorization for major procedures
  • Different reimbursement rates based on the vet type

Understanding these rules will help you avoid billing surprises.

9. Don’t Overlook Annual or Lifetime Payout Limits

Some insurance plans cap how much they will pay:

  • Per year
  • Per condition
  • Over the pet’s lifetime

Choosing limits that are too low can leave you exposed to high costs during major medical events.

10. Don’t Forget About Chronic Condition Coverage

If your pet develops a long-term illness—such as diabetes, allergies, arthritis, or heart disease—it’s essential that the policy includes chronic condition coverage that renews annually.

Some low-cost plans exclude chronic conditions or limit how long they will pay for them.

11. Don’t Ignore Dental Coverage Details

Dental illness coverage often requires:

  • Proof of annual cleanings
  • No prior dental disease
  • Full vet documentation

Some policies only cover dental accidents, not dental diseases.

12. Don’t Forget to Consider Breed-Specific Risks

Certain breeds are prone to specific hereditary or congenital issues. Before choosing a policy, check whether the insurer covers:

  • Hip or elbow dysplasia
  • Intervertebral disc disease (IVDD)
  • Heart conditions
  • Brachycephalic airway issues
  • Genetic eye conditions

Breed exclusions are more common than pet owners realize.

13. Don’t Assume Your Coverage Stays the Same Forever

Premiums often increase annually due to:

  • Pet’s age
  • Rising veterinary costs
  • Claims history
  • Insurer pricing changes

It’s important to budget for future premium increases and review your policy during each renewal.

14. Don’t Forget to Read the Fine Print

Pet insurance contracts can be long and detailed, but reviewing them prevents surprises. Pay attention to:

  • Exclusions
  • Reimbursement rules
  • Requirements for exams and diagnostics
  • Claim filing deadlines
  • Co-payment structures

Understanding these details ensures your policy performs as expected.

15. Don’t Delay Filing Claims

Some insurers require claims to be filed within:

  • 30 days
  • 60 days
  • 90 days

Missing that deadline can result in denied claims—even if the care itself was eligible.

Final Thoughts

Buying pet insurance doesn’t have to be confusing, but overlooking key details can leave you unprotected when your pet needs care most. By understanding exclusions, waiting periods, reimbursement structures, and breed-specific risks, you can choose a policy that protects both your pet and your budget.

Smart pet owners prepare before illness or injury happens—not after.
