The full picture
Courgette (called zucchini in the US) is a consistently well-tolerated vegetable for dogs. It's 95% water, very low in calories, and gentle on the stomach — a good option even for dogs with sensitive digestion. Raw or cooked both work. Spiralised zucchini 'noodles' are a common diet filler for overweight dogs. Avoid fried zucchini (too much oil) and zucchini cooked with garlic/onion. Courgette flowers are also safe and edible.

Does size or breed matter?
No specific toxicity concern from zucchini itself at any size — this is mainly a portion and preparation question. Always serve plain and cooked or chopped small where relevant, since whole or large raw pieces are a bigger choking risk for small and toy breeds than for large dogs. Introduce any new vegetable gradually, as too much fibre too quickly can cause loose stools regardless of the dog's size.
