Start small
A celebration can stay dog-friendly by keeping expectations simple and giving the dog an escape option.
There is no need to rush. A predictable, manageable step is usually more useful than trying to solve the whole situation in one day.
Try this next
Limit the guest list, set up a quiet room, and avoid forcing the dog into photos or greetings.
Notice what helps your dog stay comfortable and engaged, then repeat that version before making the situation harder.
Keep it kind and practical
Keep the next step easy enough that your dog can succeed. If you are worried about safety or feel stuck, pause and ask a qualified reward-based professional for help.
