Excessive drooling in dogs: what to do

Foamy mouth or a soaked chest often relates to nausea, oral problems or licking something irritating.

What are the common causes?

Poisoning (food / plant / chemical)

Emergency β€” go now

Chocolate, xylitol, rodenticide, antifreeze and more can be fatal; onset speed varies by toxin.

Periodontal disease

Home monitoring

80% of dogs over 3 have periodontal problems, which can seed heart and kidney disease.

Heatstroke

Emergency β€” go now

Dogs can only cool by panting β€” hot, humid or enclosed conditions (cars!) can kill within minutes.

Gastric dilatation-volvulus (GDV / bloat)

Emergency β€” go now

The stomach fills with gas and twists, cutting off circulation β€” fatal within hours; deep-chested large breeds are at highest risk.

If energy and appetite are normal with no other signs, 24-48 hours of monitoring is reasonable. Keep notes on frequency, duration, appetite, water intake, energy and what the stool/urine looks like β€” vets find this very useful.

What should I prepare before the clinic?

Note when the symptom started and how it changed; bring packaging or residue if ingestion is suspected; bring vaccination and deworming records; and if possible take a video (odd gait, cough sound) β€” clearer than describing.
