16. Apple Seeds
Apples are great for dogs — crunchy, sweet, low-calorie, full of vitamins. But the seeds are a different story. Apple seeds also contain cyanide compounds — same family as cherry pits.
The amount per seed is small. But here is the catch — dogs are not careful eaters. If they eat a whole apple core, the seeds get crushed and the cyanide releases. The core is also a choking hazard. Wash, cut around the core, toss the seeds in a sealed bin. Same for pears, peaches, plums, apricots. Next — a spice that “smells like Christmas”.
