It's 11 p.m. Your dog just threw up twice, your cat is hiding under the bed, or your puppy seems unusually quiet. Your mind races through the same question every pet owner faces: Is this a pet emergency, or can it wait until morning?
The answer matters. Acting too late on a true emergency can cost your pet their life. But rushing to the ER for a non-emergency can mean a $1,500 bill for something a regular vet visit would have solved for $150. We at PetPremium built this symptom decision guide to help you make the right call quickly — and confidently.

Before diving into specific symptoms, run this quick mental check. If you answer yes to any of these questions, treat it as an emergency and head to the ER vet immediately:
If you answered "no" to all six, you may have time to evaluate the symptoms more carefully — which is what the rest of this guide is for.
PetPremium recommends categorizing symptoms into three tiers. This is the same framework many veterinarians use during phone triage.
| Tier | Action | Timeline |
|---|---|---|
| Tier 1: True Emergency | Go to ER vet now | Within 30–60 minutes |
| Tier 2: Urgent (Same-Day) | Call your vet or urgent care | Within 4–12 hours |
| Tier 3: Wait-and-See | Monitor at home, schedule routine visit | 24–72 hours |
Let's break down what symptoms fall into each tier.
These are pet emergency symptoms you cannot ignore. Every minute counts.
This is one of the most time-critical emergencies in veterinary medicine. According to the American College of Veterinary Surgeons, gastric dilatation-volvulus has a mortality rate of 10–30% even with treatment — and is nearly 100% fatal without it.
Call the ASPCA Animal Poison Control Center at (888) 426-4435 on your way to the ER.
A blocked cat can die within 24–48 hours. This is always an emergency.
These don't require a midnight ER trip, but you shouldn't wait days. Call your regular vet first thing in the morning, or visit an urgent care clinic.
These symptoms typically resolve on their own or can wait for a routine appointment:
Important caveat: "Wait-and-see" doesn't mean "ignore." Track the symptom. If it persists past 24–48 hours, worsens, or is joined by other symptoms, escalate to Tier 2 or 1.
Some breeds are predisposed to conditions that turn ordinary symptoms into emergencies faster. This is one reason breed-specific awareness is so valuable.
Knowing the financial side helps you plan — and reinforces why prevention and insurance matter. Based on industry averages and the kinds of claims we see at PetPremium, here's what owners typically pay out of pocket:
| Emergency | Typical Cost Range |
|---|---|
| ER exam fee (just to walk in) | $150 – $400 |
| Bloodwork & basic diagnostics | $200 – $600 |
| X-rays / ultrasound | $300 – $1,000 |
| Foreign body surgery | $2,500 – $7,000 |
| GDV (bloat) surgery | $5,000 – $10,000+ |
| Hit-by-car trauma care | $1,500 – $8,000 |
| Cancer diagnosis & treatment | $5,000 – $20,000+ |
| ACL/CCL surgery | $4,000 – $12,000 |
A pet insurance policy can reimburse 70–90% of these costs, depending on your plan. Without coverage, an unexpected emergency can force the heartbreaking conversation veterinarians call "economic euthanasia."
The middle of a crisis is the worst time to figure out logistics. PetPremium recommends every pet owner do these five things now:
The reality is that 1 in 3 pets will need emergency care in any given year, according to the North American Pet Health Insurance Association. Being prepared isn't pessimism — it's love made practical.
Here's the truth no decision tree can replace: if you're unsure, call. Most emergency clinics have triage nurses who will help you decide whether to come in over the phone, and most calls cost nothing. The worst outcome of calling unnecessarily is mild embarrassment. The worst outcome of not calling is something no pet owner should have to face.
You know your pet better than anyone. If something feels wrong — even if you can't articulate why — trust that instinct.
A single episode of vomiting in an otherwise alert, energetic dog is usually not an emergency. Treat it as urgent if your dog vomits more than 3 times in a few hours, has blood in the vomit, can't keep water down, has a swollen abdomen, or is becoming lethargic. Puppies and senior dogs dehydrate faster, so escalate sooner with them.
Cats often hide when they feel sick, and skipping one meal isn't unusual. However, a cat that hasn't eaten in 24+ hours, is hiding combined with labored breathing, or is straining in the litter box should be seen the same day. Cats can develop hepatic lipidosis (a serious liver condition) within 48–72 hours of not eating, so don't wait too long.
Go to the ER for life-threatening signs: trouble breathing, uncontrolled bleeding, seizures, collapse, suspected toxin ingestion, or trauma. Use your regular vet (or urgent care) for limping, mild GI upset, ear infections, or skin issues. If symptoms appear after-hours and you're unsure, call the ER — they'll triage you over the phone for free.
The most overlooked emergencies are bloat (because owners think the dog just ate too much), urinary blockage in male cats (mistaken for constipation), and internal bleeding after seemingly minor trauma. Pale gums and a "tucked up" or distended abdomen are key warning signs that often go unrecognized until it's too late.
Most accident and illness pet insurance policies cover emergency visits, diagnostics, surgery, and hospitalization — typically reimbursing 70–90% after your deductible. Pre-existing conditions are generally excluded, which is why enrolling pets while they're young and healthy gives you the broadest coverage.
Yes. PetPremium's plans and partner policies are designed to cover unexpected accidents, illnesses, and emergency hospitalizations — the exact scenarios this guide describes. You can compare personalized quotes by entering your zip code and pet's details on our website to see what coverage and reimbursement levels fit your budget.
Veterinary professionals typically recommend keeping at least $2,000–$5,000 accessible for emergencies, since common ER scenarios (foreign body surgery, severe GI illness, trauma) frequently land in that range. For larger or breed-predisposed pets, the higher end of that range is more realistic. Pet insurance helps spread that financial risk across affordable monthly premiums instead.
Only if a veterinarian or poison control specialist explicitly tells you to — and never for cats, brachycephalic breeds, or pets that ingested caustic substances, sharp objects, or are already showing symptoms. The safer first step is always to call ASPCA Animal Poison Control at (888) 426-4435 or your nearest ER vet for direction.
