When your dog is sick, the hardest part is not knowing whether to rush to the emergency vet or wait until morning. Vomiting once after eating too fast is very different from vomiting repeatedly with a swollen abdomen. Lethargy in a 10-year-old senior means something different than lethargy in a healthy 2-year-old. This free symptom checker analyzes your dog’s specific symptoms, how long they’ve been going on, and your dog’s age and size — then returns a clear triage level, the most likely causes, and exactly what to tell your vet.
What This Tool Assesses
- A triage urgency level: Monitor at Home, Call Your Vet Today, or Go to Emergency Vet Now
- The 3–4 most likely causes ranked by probability, with distinguishing signs for each
- Specific warning signs that would escalate the situation to a higher urgency level
- Safe steps you can take at home right now while you decide next steps
- Exactly what information to have ready and what questions to ask when you call your vet
How to Use This Tool
- Select your dog’s primary symptom from the dropdown — symptoms are organized by body system
- Add a second symptom if your dog has more than one (combinations change the assessment significantly)
- Set how long the symptom has been present — duration is one of the most important triage factors
- Describe how your dog is acting right now: alert and normal vs. lethargic vs. in obvious distress
- Enter your dog’s age and breed size — puppies and seniors have different risk profiles for the same symptoms
- Click Check My Dog’s Symptoms for your triage assessment
Important: If your dog is having difficulty breathing, has collapsed, has pale or blue gums, or you suspect poisoning — do not wait for results. Go to an emergency vet immediately.
How Triage Levels Work
Monitor at Home means the symptoms are consistent with a mild, self-limiting issue — like a single vomiting episode in an otherwise alert adult dog. You should still keep a close eye on them and contact your vet if anything changes. Call Your Vet Today means the symptom combination warrants professional evaluation within 24 hours — not a middle-of-the-night emergency, but not something to leave for next week either. Go to Emergency Vet Now means the symptoms, duration, or your dog’s current condition indicate a potentially life-threatening situation that cannot wait for a regular appointment.
Why Duration and Alertness Matter More Than the Symptom Alone
The same symptom can carry very different weight depending on context. Vomiting once in an alert, playful dog who ate grass is low concern. Vomiting three times in two hours in a large breed dog with a distended abdomen is a potential bloat emergency. This tool weighs the full picture — symptom, secondary symptom, duration, alertness level, age, and size — rather than treating any one sign in isolation.

This symptom checker provides AI-generated triage guidance based on the information you enter. It is not a veterinary diagnosis and is not a substitute for professional veterinary assessment. Triage assessments are educational starting points — they cannot account for your dog’s full medical history, physical examination findings, or diagnostic test results. When in doubt, always contact your veterinarian. In a life-threatening emergency, go directly to an emergency animal hospital without waiting.
