He's been licking his paw all morning.

Got it. Is there any redness, swelling or bleeding between the toes? And is he still eating normally?

A bit red. Eating fine.

From “Something's Off” to a Clear Next Step

Most pet apps stop at information. Leo runs a full loop — check, plan, and escalate when it matters.

  1. Step 01

    Symptom Check

    Tell Leo what you're seeing in plain language: “He's been licking his paw all morning.” Leo asks targeted follow-ups — duration, appetite, energy, any bleeding — the same triage questions a vet nurse would ask on the phone.

    Output: A plain-English assessment with an urgency level — Monitor at Home, Book a Vet, or Urgent — Go Now.

  2. Step 02

    Care Plan

    Leo turns the assessment into a daily plan: what to feed, what to watch for, how long to monitor, which symptoms mean things are getting worse. The plan updates as you check in.

    Output: A day-by-day schedule with feeding times, medication reminders, and a watchlist.

  3. Step 03

    Vet Escalation

    When symptoms cross the threshold, Leo doesn't hedge. It tells you clearly, hands you a symptom summary you can read out to the vet, and helps you book from inside the app.

    Output: A one-page visit summary — timeline, symptoms, feeding changes, photos.

Every escalation rule is written against veterinary triage guidance and reviewed before it ships. Leo is built to send you to a vet early, not to keep you in the app.

Six Things Leo Handles So You Don't Have To

Breed & Body Detection

Snap a photo. Leo identifies the breed, estimates body condition score, and flags the health risks that breed is prone to — hip dysplasia in retrievers, breathing issues in flat-faced breeds, kidney concerns in older cats.

AI Nutrition Engine

Calorie targets calculated from real inputs — species, breed, weight, age, activity level, spay status, and any conditions. Leo tells you exactly how much to feed, not a vague range.

Behavior & Mood Analysis

Sudden hiding, pacing, aggression, or a change in sleep can be the first sign of pain. Leo tracks behavior patterns over time and tells you when a shift is worth a closer look.

Smart Reminders

Vaccinations, deworming, flea and tick, medication doses, weight check-ins. Timed to your pet's actual schedule, not a generic calendar.

Health Timeline

Every symptom check, weight entry, photo and vet visit in one chronological record. Export it as a PDF before an appointment.

Daily Check-ins

Leo asks how your pet is doing, learns from your answers, and quietly builds a picture of what “normal” looks like for your pet — so it can spot when normal changes.

Under the Hood

For the people who want to know what's actually running.

  1. 1

    Your pet's profile is the context.

    Leo doesn't answer generic questions. Every response is conditioned on your pet's species, breed, age, weight, medical history, current diet, and everything you've logged before.

  2. 2

    Structured tools, not free-form guessing.

    Leo doesn't just generate text — it calls dedicated functions to pull your pet's records, recalculate nutrition targets, set reminders, and write to the health timeline. That's why the answers stay consistent between sessions.

  3. 3

    A safety layer sits on top.

    Red-flag symptoms — laboured breathing, seizure, bloat signs, suspected poisoning, prolonged vomiting — bypass the conversation entirely and trigger an immediate escalation card.

  4. 4

    It remembers.

    Facts Leo learns about your pet get saved to the profile. Tell it once that your dog is allergic to chicken and it will never recommend a chicken-based food again.

Where Leo Stops

Leo is a triage and care-planning tool, not a substitute for a veterinarian. It does not diagnose disease, prescribe medication, or read lab results. It's designed to help you decide whether and how urgently to see a vet — and to make that visit more useful when you get there.

In an emergency, go to a vet or an emergency clinic immediately. Leo will always tell you to.

Questions, Answered

Is Leo a replacement for my vet?

No. Leo helps you decide when to see one and prepares you for the visit. For diagnosis, prescriptions and treatment, you need a licensed veterinarian.

Which pets does Leo support?

Dogs and cats today, across 300+ breeds and mixed breeds. More species are in development.

How accurate is the breed detection?

Leo identifies breed from a photo and will tell you when it isn't confident — including when a pet is clearly mixed. It's a starting point for risk profiling, not a DNA test.

What happens to my data if I cancel?

Nothing is deleted automatically. Your pet's history stays available and exportable. You can delete it permanently at any time from your account.

Does Leo work offline?

Reminders and your saved care plan work offline. Symptom checks need a connection.

Can I add more than one pet?

Yes. Free accounts support one pet profile; Care Leo+ Family supports up to five.
