Dogs that chew arrowhead vine get an immediate, painful surprise: the leaves and stems are packed with insoluble calcium oxalate crystals that pierce the soft tissues of the mouth on contact. Most cases stay limited to oral pain and drooling rather than progressing to anything systemic, but the dog will be visibly uncomfortable within minutes.
The first signs are almost always oral: pawing at the mouth, head-shaking, foamy drooling, and a refusal to eat or drink. You may see swelling or redness of the lips, tongue, or gums. Some dogs vomit once or twice. Difficulty swallowing, repeated retching, or any swelling that affects breathing is the more severe end of the spectrum and is uncommon but real.
Oral pain and drooling typically begin within minutes of chewing. Most cases resolve within 24 hours with supportive care; the ASPCA and Pet Poison Helpline both characterize calcium-oxalate plant exposures as generally short-lived with no lasting effects.
Call your vet (or ASPCA Poison Control at 888-426-4435) any time you see persistent drooling that doesn't subside within 30–60 minutes, visible swelling of the mouth or throat, repeated vomiting, refusal to drink water, or any change in breathing. If a small dog has chewed a large amount, call right away rather than waiting.
Remove any plant material from the dog's mouth and wipe the gums and tongue with a damp cloth. Offer something cold and palatable that contains calcium — a small amount of milk, plain yogurt, or cottage cheese — which binds the oxalate crystals and reduces pain. Do not induce vomiting; the irritation has already happened, and vomiting only re-exposes the throat to crystals. Then call your vet for guidance.
