Your Dog's Health Log

Track the things your vet will ask about.

Breathing rate, appetite, energy, symptoms — the details that matter most are the ones easiest to forget. Keep a simple daily log so you always walk into the vet's office prepared.

Everything is private. Everything stays on your device. And when you need it, you can share a clean summary with your care team.

Breathing Rate

Track resting respiratory rate — the single most important number your vet will ask about.

Appetite & Eating

Log what they ate, how much, and whether you had to coax them. Spot patterns early.

Energy & Mobility

Good day or tough day? Track energy levels, walks, and how they're moving.

Symptoms & Changes

Gum color, bloating, lethargy, bleeding — log anything unusual so nothing slips through.

Daily Notes

Free-form space for observations, vet instructions, medication changes, or just how you're both feeling.

Trends Over Time

See the bigger picture. Share a clean summary with your vet instead of scrambling to remember details.

Your vet sees your dog for 15 minutes. You see them every day.

This is how you make those 15 minutes count.

Why This Exists

When you hear the word hemangiosarcoma, everything stops.

Graffiti the Corgi — our inspiration

Graffiti — corgi, muse, best friend

Before Graffiti was diagnosed, I had never even heard the word hemangiosarcoma. Suddenly I was drowning in medical terms and timelines — and none of it told me how to just be with my dog through it.

I built HSA Days because I needed it. I needed something that wasn’t a clinical research paper or a Reddit thread full of worst-case timelines. I needed a companion — something that would meet me where I was each day and help me show up for Graffiti in the ways that mattered.

This is that thing. It’s not perfect. It’s not medical advice. It’s just one person sharing what helped, what hurt, and what they wish they’d known — so you don’t have to figure it all out alone.

— Chase & Graffiti

Information overload

You're Googling survival rates at 2 AM, reading forums that make you feel worse, and drowning in decisions you never expected to face.

Emotional isolation

Friends say 'it's just a dog.' Family doesn't get it. You need someone who truly understands this specific grief.

Every day matters

Whether your dog has weeks or months, you want to make each day intentional — not consumed by worry and regret.

HSA Days doesn’t fix any of this. But it gives you something to hold onto — one day at a time.
