Puppy safety
Broccoli (cooked) is generally safe for healthy puppies once they're fully weaned (around 8 weeks). Start with very small amounts — about 1/4 of the adult portion — and watch for any digestive upset over 24 hours before offering more. Never replace dog food with treats; growing animals need their balanced nutrition first.
