Use Caution

Apples — Feed with caution

Apple flesh (without seeds or core) is a safe and healthy treat for dogs, providing vitamins and fiber. However, apple seeds and the core contain cyanide, which is toxic if consumed in large quantities or over time. Always remove the core and seeds before offering apple slices to your dog to ensure their safety.

TOXIC COMPOUND

Cyanide (in seeds and core)

Cyanide inhibits cytochrome c oxidase, disrupting cellular respiration and oxygen utilization.

DOSE THRESHOLD

The amount of cyanide in a few apple seeds is generally not enough to cause acute toxicity in a dog. However, chronic ingestion or consumption of a large quantity of seeds can be problematic. The flesh is safe.
