Pet Emergency Decision Tool
Tell me what’s going on, or pick the closest match below. I’ll ask a few quick questions and tell you how urgent it is, what to do right now, what not to do, and exactly what to tell the vet.
⚡ Quick check first
Is any of this happening right now? If so, skip the questions — this alone is enough to tell you what to do.
What This Tool Actually Does
This isn’t a symptom checker trying to guess a diagnosis — no app can do that responsibly, and I’m not going to pretend otherwise. What it does instead: turns what you’re seeing into one of three calls (call now, call today, or watch closely at home), tells you what to do in the next few minutes, what NOT to do (some “helpful” home remedies genuinely make things worse), and hands you a clean summary to read out to the vet on the phone so you’re not fumbling for details while you’re panicking.
The thresholds behind it — chocolate toxicity by weight, why grapes have no safe amount, why a cat not eating for a day is more urgent than a dog skipping the same meal — are pulled from ASPCA, VCA, Cornell, and Merck Veterinary Manual guidance, not guessed. Sources are linked at the bottom of each result.
Why a Cat Not Eating Is Different From a Dog Not Eating
This trips up a lot of people, and it’s the reason I built cat and dog logic separately instead of treating “not eating” as one generic symptom. A healthy adult dog can usually skip a day of food and be fine. A cat is a different animal, literally — when a cat stops eating, its body starts pulling fat into the liver for energy, and a cat’s liver isn’t built to process that efficiently. That can tip into hepatic lipidosis (fatty liver disease), and it can start setting in within 48 hours, faster in overweight cats. It’s treatable if caught early, which is exactly why “wait and see” is the wrong instinct with a cat who’s refused food for a full day.
Why I Didn’t Build a Generic Symptom Checker
Type “dog vomiting” into Google and you’ll get a wall of possible causes, from mild to fatal, with no way to know which one applies to your dog right now. That’s not actually useful in the moment — it’s just more anxiety. This tool asks the handful of questions that actually change the answer (what did they eat, how much, what does the vomit look like, are the gums a normal color) and skips the rest, because at 11pm with a sick animal, you need a decision, not a differential diagnosis list.
What To Do While You’re Waiting for the Vet
- Don’t give any human medication — including “just a little” Tylenol, ibuprofen, or Benadryl — unless a vet has told you the exact drug and amount for your specific pet.
- Don’t induce vomiting unless a vet or poison control explicitly tells you to and how. For some things (sharp objects, caustic substances, petroleum products) throwing up causes more damage than leaving it.
- If you know what they ate, keep the packaging or a photo of it. The exact brand and ingredient list saves the vet real time.
- Note the time things started. “About 45 minutes ago” is far more useful to a vet than “a while ago.”
- Keep your pet calm and warm on the way in — stress and cold both make shock-like symptoms worse.
Frequently Asked Questions
Is this a replacement for calling a vet?
No — it’s the opposite of that. It’s built to help you decide how fast you need to make that call (or drive), and to make the call itself faster and more useful once you’re on the phone. If you’re ever unsure, calling a vet costs you nothing but a few minutes.
How accurate is the chocolate calculator?
It’s a real calculation using published theobromine-per-gram estimates by chocolate type (ASPCA/Merck data), not a guess — but it’s still an estimate, since cocoa content varies by brand. It’s built to round up in your pet’s favor: when in doubt, it assumes the more dangerous number, not the safer one.
My pet seems fine right now — can I skip calling the vet if this says “monitor at home”?
If your result is green, yes, watching at home is genuinely the right call for what you described — but read the “when this becomes more urgent” section anyway, since some things (chocolate, xylitol) take hours to show symptoms even when your pet seems okay immediately after.
Why does this ask about existing conditions and medications?
A senior dog with kidney disease or a cat on medication has a lot less buffer than a healthy young adult in the exact same situation. This tool bumps the urgency up a level whenever an existing condition is in play, because the safe margin for error is smaller.
What should I do if my situation isn’t covered here?
Pick “Something else” and answer the general questions — it’ll still give you a reasonable starting point. But for anything this tool doesn’t clearly cover, or if something feels off that isn’t captured in the questions, call your vet directly rather than waiting on an answer from here.
