No emergency steps. Check for thorns if the dog pushed into a hedge, and call the vet only for persistent vomiting or a infected-looking puncture.

Common questions

My dog ate fallen hawthorn berries on a walk — is that okay?

Yes. The berries are non-toxic; at most a mild stomach upset follows a large snack. Watch for nothing more than soft stool.

Are hawthorn thorns dangerous to dogs?

They can be. Thorn punctures near the eyes or in paw pads hurt and can infect, so inspect your dog after hedge encounters.
