My 7 kg dog just licked the peel of a clementine I was holding. Do I need to worry about the essential oils or a tiny bite?

Short answer

No, a single lick is not an emergency. The essential oils in the peel can cause mild stomach upset if ingested in larger amounts, but a quick lick is unlikely to do harm. Watch for any drooling or a single episode of vomiting, which would just mean his stomach is irritated. If he seems perfectly normal, offer him some fresh water and his next meal as usual. Call your own vet only if he starts repeatedly vomiting, acts lethargic, or refuses food later in the day.

Clementine — Food safety facts

Feed with care · Dogs · full breakdown on the linked food page

Flesh only, a segment or two. Peel, pith and seeds are the problem.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Clementine is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Why these cautions matter

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.

Clementine can turn up now and then, but not as a daily habit: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
