What to bring to the emergency vet — a pet owner's checklist

The problem with pet emergencies

Pet emergencies don't happen during business hours. They happen at 11 PM on a Saturday when your dog eats something off the counter, or at 6 AM when your cat won't stand up. You're panicked, your regular vet is closed, and you're driving to an emergency clinic that has never seen your pet before.

The ER vet needs to make fast decisions with incomplete information. Every minute they spend piecing together your pet's medical history is a minute they're not treating your pet. The more you can hand them upfront, the faster they can help.

What the emergency vet actually needs

ER vets will tell you the same thing: the biggest bottleneck isn't the medical part — it's the information part. Here's what they need, in priority order:

1. Current medications and doses

This is the single most important piece of information in a pet emergency. Drug interactions can be dangerous, and the ER vet needs to know exactly what your pet is taking before they administer anything. Include:

• Prescription medications (name, dose, frequency)
• Supplements and over-the-counter products
• Flea/tick and heartworm prevention (brand and last application date)
• Any medications recently stopped and why

If your pet is on no medications, that's important information too — say so explicitly.

2. Vaccination history

The ER needs to know rabies vaccination status (legally required for treatment in most states) and core vaccine history. A current vaccine tracker eliminates the guesswork.

3. Known conditions and allergies

Drug allergies, food sensitivities, chronic conditions (diabetes, kidney disease, seizure disorders), and prior surgeries all affect treatment decisions. An anesthesia reaction in 2023 matters in 2026.

4. Recent lab work

If your pet has had blood work in the last six months, that baseline is gold. The ER vet can compare emergency labs against your pet's normal values — "is this kidney value high for this patient, or is it their normal?"

Without a baseline, the ER vet has to guess. With one, they can spot problems faster.

5. What happened and when

Write down (or dictate into your phone on the drive over):

• What you noticed and the exact time
• Whether it came on suddenly or gradually
• Any potential toxin exposure (chocolate, xylitol, lilies, medications, household chemicals)
• Changes in eating, drinking, or bathroom habits in the last 24-48 hours
• Whether your pet has had this symptom before

In the stress of the moment, it's easy to forget details. Notes help.

The paperwork nobody thinks about until it's too late

Insurance information

Emergency vet visits are expensive — often $1,000-$5,000+. If you have pet insurance, having your policy number and provider ready means you can file the claim while details are fresh. Some clinics will even contact your insurer directly if you provide the info upfront.

If you've never filed a claim before, here's a guide to exporting vet records for insurance claims.

Your regular vet's contact information

The ER clinic will want to send records to your primary vet for follow-up care. Having your vet's name, clinic name, and phone number saves a phone-tag cycle later.

Payment method

Most emergency clinics require payment at the time of service. Some don't accept all insurance or offer in-house payment plans. Call ahead while you're driving (have a passenger call, or use hands-free) to ask about payment policies and estimated costs for your pet's situation.

How to actually be ready

Knowing what to bring is one thing. Actually having it accessible at 2 AM is another. Here are three levels of preparation, from bare minimum to fully prepared:

Level 1: The phone photo (5 minutes, do it today)

Take photos of your pet's current medication bottles, their most recent vaccine certificate, and their most recent lab results. Store them in a dedicated phone album called "Pet Medical." It's not organized, but at least you can hand your phone to the ER vet.

Level 2: The folder (30 minutes)

Create a physical or digital folder with organized records from your vet. Include vaccination records, lab results, any specialist reports, and a one-page summary you've written with your pet's name, age, breed, weight, conditions, allergies, and medications. Update it after every vet visit.

For tips on building this folder, see our guide on organizing pet medical records online.

Level 3: The digital health record (10 minutes setup, always current)

A pet health record app that holds everything in one place, stays current, and can be shared with any ER vet instantly. Upload your vet PDFs, and the app extracts medications, vaccines, and lab values automatically. When the emergency happens, you open the app and share a link — the ER vet sees the full picture on their screen before you even walk through the door.

That's what Voocie was built for. But any system that gives you instant access to a complete, up-to-date record works. The point is having it ready, not scrambling.

Questions to ask the ER vet

Once your pet is being assessed, you'll have time to think. Here are questions worth asking:

• What do you think is happening? Ask for the working diagnosis, not just the plan.
• What tests do you recommend, and why? Understand what each test tells you and what it costs before agreeing.
• What are the treatment options and their costs? Emergency clinics should give you a written estimate before proceeding with treatment.
• What's the prognosis? This is hard to ask but important. It helps you make informed decisions.
• When should I follow up with my regular vet? Some emergencies need follow-up within 24 hours; others can wait a few days.
• Can you send the records to my vet directly? Most ER clinics will fax or email records to your primary vet if you ask.

For non-emergency vet visits, we have a deeper list of questions to ask your vet — including when to consider a second opinion.

After the emergency

Once your pet is stable and home, take 10 minutes to do three things:

1. Save the ER records. Upload the discharge summary, any lab results, and the treatment plan to your pet's health record. Your regular vet will need these at the follow-up appointment.
2. File the insurance claim promptly. Most pet insurance requires claims within 90 days, but filing while it's fresh means you won't forget details or lose paperwork. Here's how to organize records for a claim.
3. Update your pet's medication list. The ER may have added new medications or changed doses. Make sure your records reflect the current state, not last week's.
