Is Apple Seeds Toxic to both?
Apple seeds contain amygdalin, which releases cyanide when chewed and digested. A large quantity could be fatal, but a few seeds from a single apple are unlikely to cause harm. If you suspect your both has ingested apple seeds, contact your veterinarian or nearest emergency vet clinic immediately.
If Your Pet May Have Ingested Something Toxic
Contact your veterinarian or nearest emergency vet clinic immediately. Do not wait for symptoms to appear — early intervention significantly improves outcomes.
| Toxic? | Severity | Time to Onset | Commonness | Urgency |
|---|---|---|---|---|
| Yes | Moderate | Within minutes to hours | common | moderate |
The Toxic Principle
The dangerous compound in Apple Seeds is Amygdalin (cyanogenic glycoside).
Amygdalin is a naturally occurring compound in apple seeds that releases hydrogen cyanide when metabolized. Cyanide prevents cells from using oxygen, leading to cellular suffocation. The seeds must be crushed or chewed to release the toxin — whole seeds pass through the digestive tract intact.
How Much Is Dangerous?
The risk depends on your both's weight and the amount ingested.
| Pet Weight | Dangerous Amount | Expected Severity |
|---|---|---|
| Small dog/cat (under 10 lbs) | 50-100 crushed seeds | Severe |
| Medium dog (10-50 lbs) | 100-200 crushed seeds | Moderate |
| Large dog (50+ lbs) | 200+ crushed seeds | Mild |

Frequently Asked Questions
Can my dog eat apple slices safely?
Yes. Apple flesh is safe and even healthy for dogs. Only the seeds contain amygdalin. Remove the core and seeds before giving apple slices to your pet.
How many apple seeds are toxic to a dog?
It takes approximately 100-200 crushed seeds to produce dangerous cyanide levels in a medium dog. A few accidental seeds are not cause for panic.
What about apple juice or cider?
Commercial apple juice does not contain significant amygdalin. However, homemade cider with crushed seeds could potentially contain traces.
Are apple seeds toxic to cats?
Yes. Cats are similarly affected by cyanide from apple seeds. Due to their smaller size, even fewer seeds could cause problems in cats.
