What is a dog symptom checker?

A dog symptom checker is a tool that asks about your dog's symptoms and tells you how urgent they are and what to do next. Omelo's free dog symptom checker routes each case through 500+ vet-authored decision pathways, flags red-flag emergencies, and gives a clear next step in about 30 seconds, personalized to your dog's age and history.

Is Omelo's dog symptom checker free?

Yes. It is free, with no sign-up, no card, and no trial timer. Urgent triage is never limited. The free app also includes the cat symptom checker, daily health logging, a vaccination tracker, and breed-specific guides.

When should I take my dog to the vet?

Go to a vet now for red-flag signs: repeated vomiting or diarrhea, collapse or extreme weakness, difficulty breathing, a bloated or hard belly, suspected poisoning, or pale gums. For milder signs, Omelo tells you whether it is safe to watch at home or you should book a vet within 24 hours.
