Why can't dogs have apples? - in detail
Dogs should not consume apples due to several potential health risks. The primary concern is the seeds, stems, and leaves of apples, which contain amygdalin, a compound that breaks down into hydrogen cyanide when ingested. While the flesh of an apple is generally safe for dogs, even small amounts of these toxic parts can cause serious issues.
Amygdalin, found in the seeds, stems, and leaves, releases cyanide when metabolized by the dog's digestive system. Cyanide inhibits cellular oxygen transport, leading to symptoms such as dilated pupils, difficulty breathing, and even seizures or death in severe cases. Additionally, the seeds are a choking hazard and can cause intestinal blockages if swallowed whole.
Moreover, the high sugar content in apples can contribute to dental problems and obesity in dogs. Apples also contain small amounts of tannins, which can cause stomach upset or gastrointestinal irritation in some dogs. While a small piece of apple flesh may be safe for most dogs, it is crucial to remove all seeds, stems, and leaves before offering it as a treat.
In summary, while the fleshy part of an apple might seem like a harmless treat, the potential risks associated with the seeds, stems, and leaves make apples an unsafe choice for dogs. It is always best to consult with a veterinarian regarding any dietary changes or treats for your pet.
