Can Dogs Eat Apple Seeds? Cyanide Toxicity & Care Triage
Clinical Verdict: MILD (Incidental) TO SEVERE (Large Crushed Doses)
Dogs SHOULD NOT eat apple cores or seeds. Apple flesh is a healthy snack, but seeds contain amygdalin, releasing cyanide when thoroughly chewed or pulverized in large amounts.
Toxic Mechanism & Agent
- Toxic Agent: Amygdalin (Cyanogenic Glycoside)
- Mechanism of Action: Hydrolysis in the digestive tract releases hydrogen cyanide, which halts cellular respiration by inhibiting mitochondrial cytochrome oxidase.
Clinical Signs & Timeline
- Onset Time: Signs occur within 20 to 60 minutes if seeds were chewed and absorbed.
- Primary Symptoms: Dilated pupils, bright red mucous membranes, rapid shallow respiration, weakness, staggering gait, collapse.
Emergency Triage Protocol
MONITORING (1-2 cores) / ER VISIT (Cup-fuls of chewed seeds)
If your dog ate a single apple core whole, seeds pass intact without releasing cyanide; monitor at home. If large quantities of pulverized seeds were eaten, seek immediate veterinary decontamination.
Strict Rule S1 Warning
NEVER induce vomiting at home using hydrogen peroxide without direct instruction from a DVM. Inappropriate emesis can cause fatal aspiration pneumonia. Always seek professional veterinary diagnosis.
