Why surfactants damage tissues
Surfactants in detergent dissolve cell membranes causing pain and inflammation in the mouth throat and stomach
The chemicals are absorbed quickly and can lead to vomiting diarrhea and low blood pressure
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Signs to watch for
- Repeated drooling and pawing at the mouth within minutes of exposure
- Vomiting that starts 30 minutes to 2 hours later
- Red or swollen lips and tongue
- Diarrhea that may be watery or contain blood
- Difficulty breathing if foam is inhaled
- Lethargy and weakness as dehydration sets in
What to do right now
- Call your vet or a poison control hotline right away
- Bring the detergent bottle or a label so the vet knows the exact formulation
- Do not induce vomiting because the foamy liquid can be aspirated into the lungs
- Rinse the pet’s mouth gently with lukewarm water and offer small amounts of fresh water
- Monitor for continued vomiting diarrhea or breathing problems and report any changes to the vet
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
