Your dog is going to be overwhelmed and somebody will leave a door open. The room-and-door decisions a host makes, and the two questions that belong to a vet.
Two things are going to happen at your party. Your animal is going to have a much worse evening than usual, and at some point somebody is going to leave a door open.
Both are host problems and both are solved by decisions made before anyone arrives.
What this page covers is doors, rooms and arrangements. It does not cover what an animal may eat, and it does not cover training or behavior. Those are separate subjects with separate owners, and the reasons for that boundary are at the end.
The mechanism is straightforward and it is the same every time: a door that is normally closed is now being opened every few minutes by people who do not live there and do not know there is an animal.
Front door, back door, garden gate, and the door to whichever room you have put the animal in.
Six arrangements that work:
Put the animal in a closed room before the first guest arrives, not after people start arriving. Once there is movement at the door, moving an animal becomes the thing that causes the escape.
Put a sign on that door. Actually a sign, on the door, at eye level. "Dog in here, please keep closed." Guests will not otherwise know, and a guest looking for a bathroom opens doors.
Tell people at the door. One sentence as they arrive.
Name one person to manage arrivals for the first half hour, which is when the door opens most and when the animal is most agitated.
Check the gate. If your garden is part of the party, the gate is a door too, and it will be propped by somebody carrying a tray.
Make sure identification is current before the day. Collar, tag, and whatever microchip registration you use, with a phone number that is actually yours today. This is the one item on the list that only matters if everything else has failed, and it is the one that gets it back.
Not just a closed room. A room they already like, with their own things in it, away from the noise and away from the front door.
Practical points:
Choose the room in advance and let them be in it before the party starts, so it is not a room they were shut into when everything got strange.
Water, and their own bed or crate if they use one.
Keep it dark and quiet relative to the rest of the house, and away from the wall the music is on.
Put a sign on the door and keep it closed.
Check on them, on a schedule, by one named person. "Someone will check" means nobody checks. A named person every hour or so is different.
Do not bring them out to meet people. This is the request guests make and it is the request to decline, politely and firmly. An animal in a crowded room is at the center of every risk on this page.
Genuinely worth considering rather than treated as a last resort.
A friend's house, a family member, a boarding arrangement, or a day at daycare removes every problem on this page at once. For a large or long event, particularly one with children, that is frequently the kindest available answer for the animal and the simplest for the host.
It is not an admission of anything. A house with twenty strangers, loud music and food at floor level is not an environment most animals enjoy, and choosing not to put them in it is a decision in their favor.
Worth anticipating, because none of it is malicious.
They feed the animal. Somebody usually does, often a child, often from the table. This is the one to head off in advance, and how to handle it is in the next section.
They leave bags on the floor. Bags contain things. This is the same problem children create and it has the same fix: bags go in a closed room.
They leave drinks at low level. Alcohol at animal height is a specific party-only risk.
They open doors. Covered above, and it is worth repeating because it is the one with the worst outcome.
They approach an animal that does not want to be approached. Which is why the animal is in a room with a sign on it.
Children follow the animal into its room. So the sign has to be a rule that adults enforce, not just a notice.
The pattern is the same as everything else a host arranges in advance rather than manages on the night, and it belongs on the same pre-party pass: the host's safety checklist is where those decisions live.
What an animal may or may not eat. No food, no plant, no drink and no substance is named here as safe or unsafe, and no quantity is given. That is a veterinary and toxicological question, the answers differ by species and by animal, and a partial list read by a worried host is exactly how a serious ingestion gets treated as a minor one.
If your animal has eaten something and you do not know whether it matters, that is a call, immediately. Your own veterinarian, an out-of-hours veterinary service, or an animal poison control service. In the US the ASPCA Animal Poison Control Center operates a 24-hour line; note that it charges a consultation fee. Do not wait to see whether symptoms appear, and do not attempt to treat it yourself.
Why the animal behaves as it does, and what to do about it. No training method, no calming product, no desensitization and no behavioral technique appears here. That is a separate discipline, it takes time that a party does not give you, and a host looking for a technique the night before is looking for the wrong thing. The answer available to you on the day is arrangement: a quiet room, a closed door, and fewer demands on the animal. If the underlying anxiety is a standing problem, a veterinarian is the right first conversation and can refer onward.
The reason this site draws those lines rather than covering everything is straightforward: an event page written by people who arrange parties should not be the source a worried owner relies on for a medical or behavioral judgment.

In a room they already like, with their own things in it, away from the noise and away from the front door, and settled in there before the first guest arrives rather than after. Give them water and their own bed or crate if they use one, keep the room dark and quiet relative to the rest of the house and away from the wall the music is on, put a sign on the door at eye level, and keep it closed. Name one person to check on them roughly every hour, because "someone will check" means nobody does. And do not bring them out to meet people, however nicely you are asked, since an animal in a crowded room is at the center of every risk on this page.
Treat every door as the main risk, including the garden gate, which somebody carrying a tray will prop open. Put the animal in its room before arrivals start, because moving an animal once the door is already opening is what causes the escape. Put an actual sign at eye level on that door, since a guest looking for the bathroom opens doors. Say one sentence to people as they arrive. Name one person to manage the door for the first half hour, which is when it opens most. And check the collar, tag and microchip registration carry a phone number that is current today, because that is the item that only matters once everything else has failed.
