Can dogs eat apples?
Safe. Yes, without the core. The flesh has no known toxicity for dogs.
How much is dangerous?
No toxicity in the flesh, so no threshold. Apple is about 52 kcal per 100 g. The core is a choking and obstruction risk and is the part worth removing.
Why it does harm
There is no toxic principle. Apples is on this list because owners ask about it, and the honest answer is that the risk is about calories, preparation or choking rather than poisoning.
What to look for
- None expected from the flesh. Large amounts may cause loose stool.
What to do
- Slice it and take out the core before giving any.
- Count it against the 10% treat allowance like any other extra.
