FAQ
How much causes poisoning?
Moldy nuts and black walnuts can contain tremorgenic mycotoxins (tremors, seizures) or aflatoxin (liver damage). Peak risk: fall foraging under walnut trees.
Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
