Do your best to help your rabbit relax and minimize all stressors. You know your rabbit best, so think from his perspective on what would help him feel secure in his space again.
In terms of injury, look at how he moves to see if there is any limping or oddities. You can run your hands back and forth around fur areas to check for any flinch reactions or injuries. It’ll be hard to differentiate general stress and alertness from pain right now potentially, but in a couple hours if there is still odd movements or flinching, I would recommend a vet visit for assessment.
Taking treats is a great sign. Rabbits tend to reject treats when intensely upset/distressed, physically or mentally.
I would add extra safe guards to ensure this does not happen again. Also, be mindful of carrying your dog’s scent for a while, as that may spook your rabbit due to this very negative interaction.
