Why pawing and drooling mean immediate action
Your dog's symptoms show the cleaner is already burning his mouth tissues. Alkali substances like oven cleaner don't just sit on the surface—they start breaking down proteins in the skin and mucous membranes within seconds. The foaming action means it likely spread across his tongue, gums, and possibly the roof of his mouth before he could spit it out.
Drooling is his body trying to dilute the chemical, but it won't be enough. Pawing at his face indicates pain you might not yet see—look for reddened areas or raw spots inside his lips. Avoid rubbing or scrubbing, as damaged tissue is fragile. Use a turkey baster or measuring cup to pour cool water across his teeth from the side, letting it run out of his mouth rather than swallowing.
Why vomiting would make this worse
Unlike some toxins, inducing vomiting here would be dangerous. The cleaner has already burned his mouth and throat on the way down—bringing it back up would re-expose those same delicate tissues to the alkali. It could also accidentally get into his airways, causing aspiration pneumonia on top of chemical burns.
Watch for signs like retching or coughing, which might mean some cleaner reached his stomach or windpipe. If he starts stretching his neck forward or seems to struggle swallowing, the esophagus may be swelling—this requires emergency vet care to prevent strictures that could make eating difficult long-term.
The first hour's critical window
Chemical burns continue damaging tissue until thoroughly rinsed. While you're preparing to transport him to the vet, keep flushing his mouth every 5 minutes with small amounts of water. Use about 1/4 cup per rinse for a 10 kg dog—enough to dilute residues without overwhelming him. Lift his lips to check gum color; bright red or pale gums suggest worsening irritation.
Time matters because swelling can close off his throat. If his drool changes from clear to thick or bloody, or if he starts wheezing, go straight to the emergency clinic. Bring the cleaner's container—the ingredients list helps vets gauge burn severity and choose the right pain relief and protective medications for his case.
What to expect at the vet
They'll likely sedate him to examine his mouth and throat thoroughly, checking for ulcers or deeper burns you can't see at home. They may flush his stomach with a tube to remove any swallowed cleaner safely. Intravenous fluids help protect his kidneys from processing toxins, while pain medication makes him more comfortable.
Even if he seems better after rinsing, follow-up is crucial. Alkali burns sometimes create hidden damage that shows up days later as dead tissue sloughs off. Your vet may prescribe a soft diet, oral protectants, or antibiotics to prevent secondary infections in the raw areas where his mouth is healing.
