What Is the Best Pet Insurance That Covers Everything?

You hear the phrase “covers everything” and picture your vet visits, medications, and even annual checkups all wrapped up in one monthly payment. The reality is more nuanced. Even the most comprehensive pet insurance plans exclude certain things — pre-existing conditions being the most common, and some don’t cover routine wellness care unless you add a separate rider.

The honest answer is that the best pet insurance for you depends on your pet’s age, breed, health history, and your budget. But a handful of providers consistently top the expert lists for breadth of coverage, and this article walks you through what they offer and what you still need to watch for.

What “Covers Everything” Actually Means in Pet Insurance

Most people start with the idea that comprehensive insurance means no exclusions. That’s not how pet insurance works. Standard accident-and-illness policies cover things like broken bones, cancer treatment, hospital stays, surgery, and prescription meds. Routine care — vaccinations, dental cleanings, flea prevention — usually requires a separate wellness add-on.

Even within accident-and-illness plans, coverage gaps exist. Pre-existing conditions are almost universally excluded, and many insurers have annual or per-incident benefit caps. Some plans cover exam fees; others don’t. The key is picking a policy whose exclusion list aligns with what your pet is most likely to need.

Key Coverage Areas to Compare

When evaluating a plan, look at how it handles hereditary conditions (common in purebreds), congenital issues, and behavioral therapy. Not all plans cover these equally. For example, Embrace Pet Insurance offers broad coverage that includes conditions like Addison’s disease, while some budget plans limit coverage for knee surgeries like cruciate ligament repair.

Why the “Covers Everything” Idea Sticks

Pet health insurance is still a relatively young industry compared to human health insurance. The marketing around “peace of mind” and “comprehensive care” can make it sound like one policy removes all financial risk. In reality, insurance is about transferring specific risks — not eliminating them entirely.

• The simplicity appeal: People want one payment that handles everything, so the idea of a single “covers all” plan is attractive — but the industry standard is to separate accident/illness from wellness.
• Fear of bills: A single emergency vet visit can cost thousands. The fear of an unexpected expense drives people to search for the broadest policy, sometimes overlooking what’s actually excluded.
• Marketing language: Phrases like “full coverage” or “comprehensive” are used loosely. Each company defines them differently, making direct comparisons tricky.
• Lack of standardization: Unlike car insurance, there’s no mandatory minimum coverage framework. Each provider sets its own terms, so “everything” varies wildly by policy.

Understanding why the phrase can be misleading helps you look past the marketing and compare policies on specific features that actually matter for your pet.

The Top Contenders for Comprehensive Coverage

Several insurers earn consistent praise from independent reviewers. ASPCA Pet Health Insurance is named best overall by U.S. News and NerdWallet, offering customizable accident-and-illness and accident-only plans. AKC Pet Insurance stands out because it can cover some pre-existing conditions after a 365-day waiting period — a unique feature covered in the New York Times Wirecutter review of AKC Pet Insurance preexisting options.

Other strong contenders include Pets Best (best budget option per U.S. News), Spot (best perks and multi-pet discounts), and Embrace (best unlimited annual coverage). Nationwide offers coverage that applies at any vet, specialist, or emergency room, with automatic claims submissions. The Wall Street Journal’s Buy Side also places Pets Best and Spot among its top picks.

Each of these providers has strong reviews, but which one feels like “everything” for your pet depends on what conditions and services you most want covered.

What Most Plans Exclude—and How to Work Around It

The biggest gap in any “covers everything” claim is pre-existing conditions. Most pet insurance policies permanently exclude any illness or injury that showed signs before enrollment. A few insurers, like AKC, will consider covering a pre-existing condition if the pet has been symptom-free and treatment-free for 365 days. Other exclusions include certain breed-specific issues (though many plans now cover hereditary diseases), and some plans cap coverage per incident or annually.

1. Enroll your pet early: The best way to avoid pre-existing exclusions is to get a policy when your pet is still healthy. ASPCA Pet Health Insurance recommends enrolling sooner rather than later because conditions can appear suddenly.
2. Ask about curable pre-existing conditions: Some insurers, including Petinsurance.com, note that if a condition is fully resolved and documented as cured (e.g., a urinary tract infection), it may be covered in future policies. Always check individual company rules.
3. Read the waiting periods: Most plans have a short waiting period (2–14 days) for accidents and a longer one (6 months or more) for certain orthopedic conditions. Know the timeframes before you need care.
4. Consider wellness add-ons: If routine care is part of your “everything,” choose a plan that offers a wellness rider — otherwise, those costs come out of pocket.

The bottom line on exclusions: no policy covers everything, but you can minimize surprises by reading the fine print and asking directly about conditions common to your pet’s breed.

How to Choose the Best Plan for Your Pet

Start with your pet’s current health and age. A young, healthy dog might benefit from a lower-premium plan with a higher deductible, while an older pet with a known condition needs a policy that either covers that condition (if curable) or offers high annual limits for new issues. Multi-pet households should factor in discounts — Embrace and Spot both offer multi-pet discounts that can make comprehensive coverage more affordable.

Per NerdWallet’s analysis of top pet insurance companies, ASPCA Pet Health Insurance leads for comprehensive coverage, Spot offers the best perks, and MetLife is the top choice for short accident waiting periods. You can see full rankings on the NerdWallet top pet insurance page.

The Bottom Line

No pet insurance covers everything, but the best comprehensive plans — ASPCA, AKC, Spot, Embrace, and others — get very close for the things that matter most: accidents, illnesses, surgeries, and chronic conditions. The key is matching a plan’s specific coverage to your pet’s breed, age, and any pre-existing history. Reading independent reviews from sources like U.S. News, NerdWallet, and the Wall Street Journal helps cut through the marketing.

If your dog is a purebred prone to hip dysplasia or your cat has a history of urinary issues, ask your veterinarian whether a particular plan’s coverage limits for those conditions fit your pet’s likely needs — your vet’s experience with local claims can be surprisingly useful guidance.
