Why apple seeds are dangerous
Apple seeds contain amygdalin, a compound that breaks down into hydrogen cyanide when chewed.
Cyanide blocks the cells’ ability to use oxygen, leading to rapid organ failure.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of apple-seeds poisoning
- Repeated vomiting within 30‑60 minutes after eating the seeds
- Rapid breathing and panting appearing within an hour
- Weakness and stumbling by the afternoon
- Bright red or pink gums within 2‑3 hours
- Seizures or uncontrolled shaking in the evening
- Collapse or unconsciousness if untreated
What to do right now
- Call your vet or the Pet Poison Helpline right away
- Bring a sample of the seeds or the apple piece if possible
- Keep your pet calm and monitor breathing
- Do not induce vomiting because the cyanide can be absorbed quickly
- If breathing stops, begin CPR and transport to an emergency clinic
