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.

Arrow-head vine is toxic to both cats and dogs due to the presence of insoluble calcium oxalate crystals.
Yes, the arrowhead plant (Syngonium podophyllum) is toxic to dogs. It contains insoluble calcium oxalate crystals that cause immediate oral irritation, excessive drooling, vomiting, difficulty swallowing, and pawing at the mouth upon ingestion.
The first signs appear within minutes and are almost always oral: pawing at the mouth, head-shaking, foamy drooling, and refusal to eat or drink. You may also see redness or swelling of the lips, tongue, or gums, and some dogs vomit once or twice. Difficulty swallowing or swelling that affects breathing is uncommon but represents the more severe end of the spectrum.
Remove any plant material from your dog's mouth and wipe the gums and tongue with a damp cloth. Offer something cold containing calcium — a small amount of milk, plain yogurt, or cottage cheese — which binds the oxalate crystals and reduces pain. Do not induce vomiting, as this only re-exposes the throat to the crystals. Then call your vet or ASPCA Animal Poison Control at (888) 426-4435 for further guidance.
Oral pain and drooling typically begin within minutes of chewing and most cases resolve within 24 hours with supportive care. The ASPCA characterizes calcium-oxalate plant exposures as generally short-lived with no lasting effects. However, call your vet right away if drooling persists beyond 30–60 minutes, swelling affects breathing, or a small dog has chewed a large amount.
