Symptoms to Watch For
🐕 In Dogs
- Drooling, vomiting, and mouth/throat burning within minutes to hours
- Coughing, choking, wheezing, or rapid breathing (aspiration into the lungs)
- Lethargy, wobbliness, and weakness
- Tremors and low body temperature in larger exposures
- Skin redness or chemical burns where the liquid contacted fur and skin
🐈 In Cats
- Drooling, vomiting, and mouth irritation
- Coughing, rapid or labored breathing from aspiration
- Weakness, wobbliness, and lethargy
- Skin irritation or chemical burn where liquid contacted fur
What to Do If Ingested
- Do NOT induce vomiting — hydrocarbons aspirate catastrophically into the lungs.
- Move the pet to fresh air if fumes are strong.
- Wash skin contact off with mild dish soap and lukewarm water.
- Call a vet or poison hotline immediately and monitor breathing closely for 24 hours.
Steps apply to both cats and dogs. When in doubt, call a vet or poison hotline before acting. Have a cat? Run the Pet Poison Triage Wizard for cat-specific steps.
When to Call the Vet Immediately
Call your veterinarian or a poison control hotline right away if you notice any of these:
- Any hydrocarbon liquid was swallowed — even a mouthful
- Coughing, wheezing, rapid or labored breathing — emergency
- Wobbliness, tremors, or collapse
- Large skin exposure or any burn-like redness
Frequently Asked Questions
Frequently Asked Questions
Why is vomiting so dangerous with these products?
Hydrocarbons are extremely slippery and volatile — when vomited, they foam and are easily inhaled into the lungs, where they cause chemical aspiration pneumonia that can be fatal. The gut irritation from a small swallow is far less dangerous than the lung damage from one aspiration event. This is the classic "never induce vomiting" toxin: rinse the mouth, wash the skin, and let professionals handle decontamination.
What about the fumes — is being in the garage with the moped enough?
Ordinary brief exposure to fumes in a ventilated space causes little harm, but a pet shut in a space with open containers or strong fumes can develop drooling, dizziness, and breathing irritation. The real hazards are ingestion of pooled liquid (drip pans, open gas cans, grill starter) and skin contact, both of which absorb and cause systemic signs. Store fuels in sealed containers off the floor.
My dog stepped in gasoline and then licked its paw. What should I do?
Wash the paw (and any splashed fur) immediately with mild dish soap and lukewarm water — do not use solvents or anything harsher. Offer water, then watch closely for 24 hours: coughing, wheezing, drooling, vomiting, or wobbliness all mean a vet visit now. A single paw-lick of gasoline is unlikely to be fatal, but it is not a "wait and see" toxin — make the call.
