Eggnog stacks four separate dog problems in one glass: rich dairy, sugar, nutmeg, and often alcohol. A stolen lick of plain store-bought nog is usually just a stomach risk; spiked eggnog is different, because alcohol is genuinely toxic to dogs even in small amounts.

Why Eggnog needs caution
No single ingredient makes eggnog dangerous; the recipe does. The dairy and fat are a stomach-upset and pancreatitis question. The ASPCA lists alcohol as toxic to dogs, causing vomiting, incoordination, depressed breathing, and worse, and a spiked batch turns a countertop spill into a real exposure. Nutmeg contains myristicin, which Pet Poison Helpline flags for tremors and agitation at large doses, though a drink-level sprinkle is a small amount. Homemade nog adds raw egg, a Salmonella risk the ASPCA notes for raw diets.
The holiday-party spill
The typical exposure is a dog cleaning up a knocked-over glass or an unattended cup at nose height. A few laps of non-alcoholic nog is a monitor-at-home event. The same few laps of rum-heavy homemade nog can matter for a small dog, because dogs are far more sensitive to alcohol than the drink's taste suggests. When you do not know which glass it was, treat it as spiked.
Signs to watch for
Gas, vomiting, loose stool; with alcohol, stumbling, drowsiness, slowed breathing; with a large nutmeg dose, tremors or agitation
What to do next
Figure out whether the nog was spiked before anything else. If it was, call your vet or poison control now with your dog's weight and a volume estimate; if not, treat it as rich dairy and monitor.
A lick or two of unspiked nog is a low-risk exposure for a medium or large dog. Volume, body size, and above all the recipe move the needle: alcohol content is the deciding factor, and a small dog that drank from an abandoned spiked glass is an act-now case rather than a watch case.
Can I treat this at home?
Yes, for a small amount of non-alcoholic eggnog. Expect possible gas or loose stool and skip other rich food for a day.
When should I call the vet?
Any spiked eggnog beyond a trace, any amount in a small dog, or signs like stumbling, drowsiness, vomiting that repeats, tremors, or unusual agitation. Alcohol signs in a dog are an emergency, not a hangover.
Can I make a dog-safe eggnog?
There is no version worth building. The appeal to a dog is the fat and sugar, which are the parts that cause trouble. A spoon of plain yogurt or a lick of plain whipped cream is a smaller dose of the same reward without the nutmeg, alcohol, and raw-egg questions.
