Yes. Apple flesh is safe and a good low-calorie treat for dogs. The core and seeds should be removed first — apple seeds contain a compound that releases cyanide when broken down, though the real-world risk from a few accidentally swallowed seeds is low.
Apple seeds contain amygdalin, a cyanogenic compound that can release small amounts of cyanide when the seed coating is broken (chewed or ground), rather than swallowed whole. In practice, the amount in the few seeds from an apple core is far below a toxic dose for a dog of almost any size — the concern scales with large quantities of crushed seeds (such as from commercial apple waste or a dog getting into a big bag of seeds), not from a dog eating apple slices with the core removed.
The more realistic everyday risk is the core itself as a choking or obstruction hazard, particularly for smaller dogs.
