What Is October 27? The Day Pets Come Back for Día de los Muertos

What Is October 27 Pet Day?

October 27 pet day refers to the belief, held in many Mexican communities, that the souls of deceased pets return home ahead of Día de los Muertos. It isn't one fixed nationwide rule: families build altars, called ofrendas, with water, food, and photos to welcome a dog or cat's spirit before the main November 1 and 2 observance.

The custom has grown fast enough that Mexico's National Anthropology and History Institute now shares guidance on its own social channels for including pets on Día de los Muertos altars, according to the Associated Press. Families treat October 27 as a quiet prelude to the larger holiday: a chance to set out a photo, a bowl of water, and a favorite treat before the main remembrance days arrive.

This isn't centuries old in the way the human-focused holiday is. It reflects how dogs and cats have shifted, in many households, from companion to family member, and how grief for them is finally getting a place on the calendar. Exactly how a family marks the day, with a full altar or a single candle, depends heavily on region and household. No single governing body hands down one script that every family in Mexico, or in the diaspora, follows the same way.

Is October 27 an Official Holiday for Pets, or a Newer Unofficial Custom?

October 27 is not a government-mandated holiday in Mexico. It's a newer custom layered onto the older Día de los Muertos framework, and every source tracking its spread describes it as an adaptation still taking shape, not a settled tradition with one fixed history.

The Associated Press reports that the practice has gained enough traction that Mexico's National Anthropology and History Institute now includes tips for pet altars on its social platforms. Juan Pablo García Urióstegui, an ethnohistorian at Mexico's National Anthropology Museum, told Vice that the shift is happening in real time, tying it to demographic change: couples without children increasingly treat pets as their kids, which is drawing death rituals once reserved for people toward animals too.

"We are experiencing changes in the traditions. It is happening very fast."

Dating the custom itself gets murkier the further back you look. An azcentral report traces the pet-offering tradition to 2019, when a Mexico-based pet funeral company first proposed the commemoration. A Merca20 report adds that some advocates floated October 27 only in 2020, after earlier proposals had suggested November 3 instead. That makes the custom about six to seven years old, depending on whether you date it from 2019 or 2020, not an ancient fixed observance. Treat regional and family variation as the rule here, not the exception.

How Does October 27 Fit Into the Larger Día de los Muertos Sequence Through November 2?

October 27 opens the pet-focused stretch of Día de los Muertos rather than standing alone. It's the day many families welcome a pet's spirit home, and it leads directly into the human-focused dates that follow, with some households keeping pet altars standing for several days afterward.

1. Before October 27: families set up the ofrenda before October 27, according to the site's own Día de Muertos for pets guide, so it's ready when the spirit is believed to arrive.
2. October 27: pets' souls are welcomed home, the start of the sequence.
3. November 1: Día de los Inocentes, dedicated to the souls of children and infants, according to Vice's Sammi Caramela.
4. November 2: the Day of All Souls, honoring adults, per the same Vice reporting. If your dog died and you want a gentle way to mark this specific date, All Souls' Day for pets covers how to do that without needing a formal church rule.
5. Through at least November 3: some families leave the ofrenda in place a bit longer, according to the site's Día de Muertos for pets guide, to make sure the spirit has a proper send-off before the season closes.

None of these steps are mandatory in sequence. A family can observe only October 27, only November 2, or the whole stretch.

Is October 27 Also International Black Cat Day?

Some search results connect October 27 to an unrelated cat-awareness observance, which can make the date confusing to search for. Public detail on that cat-specific observance is limited in the sources used for this article, so we aren't going to assert dates, origins, or claims about it here.

This article's focus stays on the Día de los Muertos pet custom: the day many families, particularly in Mexican and Mexican-diaspora communities, welcome home the spirits of dogs, cats, and other animal companions ahead of the main November observance. If you arrived here searching for a cat-specific holiday on the same date, that's a separate tradition with its own history, one this piece doesn't have reliable sourcing to describe. What's well documented is the pet-remembrance custom tied to Día de los Muertos, and that's what the rest of this guide covers.

Why Dogs Are Central to This Tradition: The Xoloitzcuintli Story

Dogs hold a specific, ancient role in this tradition that predates the modern pet-altar custom by thousands of years. The Xoloitzcuintli, the Mexican hairless dog, was considered a sacred guide to the afterlife by the Aztec and Maya, according to Vice. That belief is the reason dogs, more than any other animal, anchor this observance.

Aztec and Maya tradition held that the Xoloitzcuintli accompanied human souls across the underworld river, acting as both protector and intermediary between the living and the dead. Families sometimes buried a Xoloitzcuintli alongside its owner to fulfill that duty. The site's own research on the tradition notes that today, people echo this belief by placing ceramic Xoloitzcuintli figurines, or simply a photo of their own dog, on the ofrenda, standing in for that same role of guidance and companionship.

That history makes the dog-guide symbolism itself ancient, stretching back to pre-Columbian belief. The dedicated October 27 observance for pets is a modern layer on top of that old symbolism, traced by sources to proposals as recent as 2019 and 2020, not a custom whose current form goes back centuries.

What Goes On a Pet Ofrenda on October 27?

A pet ofrenda is built around a handful of core elements, each standing in for something the spirit is thought to need on its journey. The site's own guide to the tradition lists a photo of the pet, water, food or treats, candles, and marigolds, known as cempasúchil, as the basics most families include.

The photo sits at the center, since it's the clearest signal to a returning spirit that it's remembered and welcome. Water and food represent nourishment for the journey; candles represent light to guide the way; marigolds are believed to lead the spirit to the altar through their color and scent. Many families add personal items too: a collar, a favorite toy, a blanket that still carries the dog's scent.

That's the short version. Building a full, safe ofrenda, including how to keep candles and small items away from other pets, and ideas for species beyond dogs, deserves more space than a quick overview can give it. The site's dedicated guides on Day of the Dead for Pets 2026 and Día de Muertos for pets walk through construction, placement, and safety in detail, including how long to leave the altar up.

How to Observe October 27 Respectfully If It Isn't Your Family's Tradition

You don't need Mexican heritage to grieve a dog, and you don't need to perform someone else's ritual to prove your grief is real. If October 27 speaks to you, a quiet, honest version of it, a photo set out, a bowl of water, a few minutes spent remembering, is enough. There's no requirement to build a full ofrenda you don't understand just to feel like you're "doing it right."

This is a Mexican tradition, rooted in specific beliefs about the Xoloitzcuintli, the underworld journey, and a calendar that culminates on November 1 and 2. Acknowledging that origin, rather than turning the ritual into decoration or a costume theme, is the difference between honoring a practice and flattening it.

This also matters if you're the one supporting a grieving friend rather than grieving yourself. Dismissing their pain with "it's just a dog" is its own kind of harm, one this day when your pet is gone guide addresses directly for anyone who feels pressure to perform cheerfulness they don't feel on a day meant to mark loss.

When Is the Next October 27 Pet Day, and What If You Missed This Year's?

The next October 27 pet day falls on October 27, 2027, one year after this year's observance on October 27, 2026, which has already passed as of this writing. That's not a reason to feel you've missed your chance to remember a dog who died.

Grief doesn't run on a calendar, and neither does your right to mark it. If the date slipped by, you can still set out a photo tonight, light a candle this week, or simply sit with a memory whenever it feels right. The custom's own history supports that flexibility: sources trace its modern form to proposals made as recently as 2019 and 2020, which means even the people who shaped this tradition were figuring out the timing as they went.
