Symptoms · Causes · What To Do

Your dog is sick. You searched. Here's the honest answer.

If your dog is vomiting, has diarrhea, or seems lethargic — and you're trying to figure out what's going on at 11pm with a search bar — start here. We've put together plain-English guides to each major panic-search symptom, the realistic causes behind it, and the one most owners never check: their own yard.

We'll direct you to the closest 24/7 vet.

Two fields. Once your dog is okay, we'll follow up with a short call to help you check the yard for what caused it — because most repeat episodes start there.

Used only to text the closest vet and one follow-up call about your yard. No marketing, no sharing.

This is educational, not medical advice. Humane Paws is a Seattle yard sanitation company, not a veterinary clinic. If your dog is showing severe or persistent symptoms — repeated vomiting, bloody diarrhea, refusing food for over 24 hours, lethargy, or signs of dehydration — call your veterinarian or a 24/7 emergency animal hospital immediately.

The common thread

Most recurring symptoms have one thing in common — the yard.

A single bout of vomiting can be a piece of cheese off the counter. But when symptoms recur — when your dog seems to keep getting sick despite vet visits, dewormings, and the same prescription bag of food — the cause is almost always environmental, not internal.

Untreated yards are biological reservoirs for parasite eggs, bacterial loads, and viral particles that survive in soil for weeks, months, or even years. A treated dog returning to a contaminated yard is the textbook way to keep a problem alive.

Right-now checklist

If your dog is sick tonight, here's what to do in the next hour.

What matters most for good outcomes is recognizing severity early. These are the gates vets use to triage urgency at intake.

Take their temperature

Normal: 101–102.5°F. Fever is a same-day call.

Check gum color

Pink and moist = normal. Pale, white, yellow, blue = emergency.

Check hydration

Pinch the skin between shoulder blades — should snap back instantly.

Note timing & contents

When did it start? What did it look like? What were they doing first?

Walk the yard

Anything new? Plants, mushrooms, standing water, accessible compost?

Vaccine status

Parvo & lepto especially. Unvaccinated + symptomatic = vet now.

Once your dog is okay

The yard is the part that's been hiding in plain sight.

If your dog has been sick more than once, or you've been chasing the same symptoms through round after round of treatment — a clean dog in a contaminated yard is the textbook setup for the cycle continuing. Humane Paws is the part of yard care that addresses what's actually in the soil. We'd love to walk your yard, talk through what we'd do, and send a transparent quote. Free and on-site.
