Is this an emergency, or can you wait?

When your dog or cat suddenly seems off, it is hard to think clearly. This short decision tree helps you sort the symptom into one of three paths: emergency vet now, home care with monitoring, or call your regular vet soon. It is not a diagnosis. If you are unsure, call a vet.

Last updated 2026. Written for dogs and cats. Based on common triage patterns, not lab results. Always double-check with your veterinarian.

Start the triage

Pick your pet type, then choose the main symptom you are seeing. Answer the follow-up questions as they appear. You can restart any time.

Step 1. What kind of pet?

Common poisoning substances for dogs and cats

Many everyday items can poison pets. If your pet ate something on this list, call your vet or a pet poison helpline right away. Do not wait for symptoms.

Dogs

Cats

This list is not complete. If you are not sure whether something is toxic, call your vet or an animal poison control center. Bring the package or plant photo with you.

Home first-aid kit checklist for pets

Keep a small kit in one place so you are not searching during a crisis. You do not need a full veterinary hospital. A few useful items will help you stabilize your pet and keep them calm until you reach the clinic.

Check the kit twice a year. Replace anything expired or used. Ask your vet before giving any medicine, even over-the-counter products.

When-to-call-your-vet script template

When you call the vet, it helps to have a short script ready. This keeps you from forgetting important details while you are stressed. Read it off your phone or write it down.

"Hi, I need to talk to a vet or nurse about my pet."

"My pet is a [dog/cat], about [age] years old, [breed or mix]."

"The main problem started [time] ago. The symptom is [what you see]."

"They are [eating / not eating], [drinking / not drinking], and [active / weak / hiding]."

"They have eaten today: [list food, treats, or anything unusual]."

"They are on these medicines: [list]."

"They have these health problems: [list]."

"Do I bring them in now, or can I watch them at home?"

"What signs would mean I should come in right away?"

If the clinic is closed, ask for the nearest emergency hospital. Save that number in your phone before you need it.

How this decision tree works

The tree asks a small number of questions and then sorts your pet into one of three paths. Emergency means go now, even if it is the middle of the night. Home care means you can treat minor issues while watching closely. Call soon means the problem is not an immediate crisis but still needs a vet within a day or two.

The questions are based on common triage patterns used by veterinary staff when owners call with concerns. They are not a substitute for an exam. If your pet seems to be getting worse, skip the tree and call.

Common mistakes people make

Assumptions and limits

This guide assumes your pet is otherwise healthy and is not already under vet care for a serious chronic illness. If your pet has diabetes, heart disease, kidney disease, or is very young or very old, you should call a vet earlier rather than later. The tree also cannot cover every rare condition. Use it as a starting point, not a final answer.

Scenario walkthrough

Your dog ate half a bag of sugar-free cookies an hour ago. You pick "Dog" and then "Ate something unusual." The follow-up asks whether the product contains xylitol. You check the package and say yes. The tree sends you straight to emergency vet now, because xylitol can cause sudden liver failure in dogs. You call the clinic on the way and bring the cookie package with you.

Your cat has vomited twice today but is still eating and playing. You pick "Cat" and "Vomiting." The follow-up asks about energy level and how often the vomiting has happened. The tree suggests home care with monitoring for the next 12 to 24 hours. It also tells you the warning signs that should make you switch to calling the vet.
