What to Tell Your Vet About Your Dog's Symptoms

June 25, 2026

Short answer

Tell your vet what you're seeing, when it started, whether it's getting better or worse, and what else has changed: appetite, energy, bathroom habits, and anything your dog might have eaten. The clearer and more specific you are, the faster your vet can help.

Most owners freeze up in the exam room and forget half of what they meant to say. Walking in with a few organized notes changes the whole visit.

Start with the basics

Before you describe symptoms, give your vet the context that shapes everything else:

  • Your dog's age, breed, and size
  • Whether they're spayed or neutered
  • Any ongoing conditions or current medications (including supplements and flea/tick preventives)
  • Any recent changes: new food, travel, boarding, a groomer, a new pet

The same symptom means different things in a 12-year-old dog on daily medication versus a healthy 2-year-old, so this context matters more than people expect.

Describe each symptom clearly

For everything you've noticed, try to cover four things:

  1. What exactly you're seeing

    Be concrete. "Breathing fast with his belly moving a lot" tells your vet more than "trouble breathing."

  2. When it started

    Note whether it came on suddenly or gradually.

  3. How often it happens

    Include how long each episode lasts.

  4. Better, worse, or the same

    Say how it has changed since it began.

If it helps, count it: "vomited three times since last night" is far more useful than "vomiting a lot."

The details owners forget

These are the ones that most often get left out, and they're often the ones that matter:

  • Appetite and water: eating less, refusing food, drinking more or less than usual
  • Bathroom habits: frequency, consistency, color, any straining
  • What they might have gotten into: trash, human food, plants, medications, chemicals, even if you're not sure
  • Anything you've already tried at home, and whether it helped

Bring these with you

  • Photos or video of the symptom, especially anything that comes and goes (a cough, a limp, shaking). It's hard to reproduce on demand in the exam room.
  • A list of medications and doses
  • The food or treat brand, if diet is part of what's going on
  • Vaccination records, if you have them handy
