Best Dog Advent Calendars and Cat Advent Calendars for 2026: Vet-Reviewed Picks

A dog advent calendar turns December into a daily surprise, and that daily habit is where most of the trouble starts. Twelve to 24 extra treats can quietly use up a small dog's calorie allowance, and a calendar toy that fits entirely in a big dog's mouth is a choking risk, not a present.

This guide sorts the 2026 calendars we would buy by what is actually inside each dog advent calendar: treats or toys, piece size, ingredients, and number of days. It applies the veterinary 10 percent treat rule, covers the two cat advent calendars worth buying, and explains how to keep the countdown from upsetting a stomach.

Buy early. Holiday calendars are a seasonal product, so the practical plan is to order by early November and leave room for ship time.

What to look for in a dog advent calendar

Two things matter more than the artwork on the box: treat calories against your dog's daily diet, and toy size against your dog's mouth and chewing style. For small dogs, our top pick is the Frisco Holiday Advent Calendar for Small Dogs. For medium and large dogs, it is the BARK Christmas Advent Calendar.

The calorie side comes down to the 10 percent treat rule. VCA Animal Hospitals says treats should be limited to 10 percent of a dog's daily calorie intake. A review in Veterinary Sciences notes that WSAVA and AAHA both use the same 10 percent ceiling for treats and other non-complete foods.

VCA's obesity guidance gives a worked example: a dog with a 1,000-calorie daily target gets 900 calories from its regular diet and 100 from treats or snacks. That 100 calories is the whole budget for the day, calendar door included.

Treat size is where a dog biscuit advent calendar can go wrong. VCA notes that one large milk-bone style biscuit carries about 85 calories. On that 1,000-calorie day, a single large biscuit would use 85 of the 100 treat calories. A smaller dog has a smaller total, so the same biscuit takes an even bigger share.

That is why piece size matters more than door count. VCA advises choosing lower-calorie treats and saving high-value, high-calorie treats for less frequent use. A dog advent calendar with treats in small, breakable pieces is easier to fit into a small dog's day than one built around full-size biscuits.

Ingredients are the second filter. The Merck Veterinary Manual lists the most common food allergens in dogs as:

• Beef
• Dairy products
• Chicken
• Wheat
• Lamb

Merck also notes that food allergens hide in treats, supplements, and flavored medications. If your dog has a known food allergy, read the full ingredient list on any advent calendar for dogs before the first door. For any dog, VCA suggests giving only a small piece of a new treat at first.

Whether you pick up a dog advent calendar near you at Costco, Sam's Club, Petco, or PetSmart, or order a Christmas dog advent calendar online, use the same checklist:

• Contents: treats, toys, or a mix of both
• Days: a 12-day countdown means fewer extra treats than a 24-day one
• Piece size: small enough to fit the calorie budget, large enough that a toy cannot be swallowed
• Ingredients: checked against your dog's known allergies
• Calories per piece: printed on the label, since no general figure applies to every calendar

Themed boxes deserve the same scrutiny. A Grinch, Dog Man, or Disney design on the front tells you nothing about what is behind the doors. Some calendars marketed to dog lovers are made for people, not dogs, so confirm the box says it is a dog xmas advent calendar meant for pets before it goes under the tree.

Our picks: the best dog advent calendars and cat advent calendars for 2026

The best dog advent calendar for your dog is the one whose contents fit its size and diet, not the one with the most doors. A small dog advent calendar and a large dog advent calendar should differ in piece size and toy size, not just box size.

All seven picks come from Chewy, which listed each one in stock in October 2026. We have not hands-on tested them. The picks rest on published contents, ingredients where available, and veterinary feeding and toy-safety guidance. Where a listing gives only the name, size, and price, we say so.

Shopping a Costco, Trader Joe's, Aldi, Target, Petco, PetSmart, or Amazon dog advent calendar instead? The comparison table below works as a checklist for any box, including leftover 2025 stock. The questions are the same: what is inside, how many days, how big each piece is, which dog size it suits, and which allergens it contains.

Frisco Holiday Advent Calendar for Small Dogs: best overall for small dogs

From ChewyIn stock

Frisco Holiday Advent Calendar for Small Dogs, Small, 12 count

A 12-toy Frisco holiday countdown built for small dogs.

$24.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

This is Frisco's holiday advent calendar in its small-dog version, sold as a 12 count. Chewy listed it at $24.99 in October 2026, which puts it in the middle of this list on price.

It suits small dogs and owners who want a shorter countdown. Chewy's listing describes 12 toys, one per day: five squeaky plush toys plus small balls, a rope ball, a knotted fetch toy, and tennis ball toys. With no treats inside, it adds nothing to a small dog's 10 percent treat allowance.

The tradeoff is toy size. The balls and tennis ball toys are sized for small dogs, so keep them away from bigger dogs in the house, supervise play with each new toy, and retire any plush toy once stuffing starts to show.

BARK Christmas Advent Calendar: best for medium and large dogs

From ChewyIn stock

BARK Christmas Advent Calendar Plush Toy & Treat Set, Multicolor

BARK's plush toy and treat advent set for bigger dogs that enjoy a daily toy as much as a daily treat.

$59.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

BARK's own listing for its toy and treat advent calendar describes 24 surprises, one per day: 8 holiday-themed plush toys in one size and 16 treats across 6 types. The box measures 8 by 10.78 by 16.88 inches. The Chewy set, listed at $59.99, may differ in exact contents by retailer and year, so check the box you receive.

It is the pick for medium and large dogs that enjoy plush toys and play gently. Mixing toys into 8 of the 24 days also means fewer treat days than an all-treat calendar of the same length.

The tradeoffs are the ingredients and the toy size. BARK lists these in all six treat types:

• Whole wheat flour and spelt flour
• Applesauce, honey, and cinnamon
• Oat hulls
• Peanuts and coconut

The frosted treats add sugar, hydrogenated palm kernel oil, soy lecithin, vanilla, and dried whey, and the treats are colored with FD&C dyes. That rules this box out for dogs sensitive to wheat, peanuts, dairy, or soy. Because the toys come in one size, confirm each one is too big to fit entirely in your dog's mouth.

Country Kitchen Holiday Dual Bites Advent Calendar: best treats-only pick

From ChewyIn stock

Country Kitchen Holiday Dual Bites Advent Calendar Crunchy Dog Treats, 6.7-oz box

A crunchy, treats-only advent calendar in a 6.7-oz box, the lowest-priced dog pick here.

$8.89

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

This is a treats-only advent calendar of crunchy dual-bite treats in a 6.7-oz box. At $8.89 on Chewy in October 2026, it is the lowest-priced dog calendar on this list.

It suits households that want the daily ritual without any toy to supervise, and dogs that already do well on crunchy treats. Chewy's listing says the treats are made with real chicken, so skip this box for a dog that reacts to chicken. With no toys inside, there is nothing to chew apart or swallow whole.

The tradeoff is that every door is food. Each treat counts toward the 10 percent allowance, so trim your dog's meals to match. The door count and full ingredient list are printed on the box rather than confirmed in the listing, so check both before you start, especially for a dog with a known food allergy.

Disney Table Scraps Jerky Advent Calendar: best jerky-treat calendar

From ChewyIn stock

Disney Table Scraps Advent Calendar Chicken, Turkey, Beef, & Duck Jerky Dog Treats, 7-oz bag

A jerky-only advent calendar with chicken, turkey, beef, and duck, for dogs that skip wheat-based biscuits.

$24.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

This calendar fills its doors with jerky made from chicken, turkey, beef, and duck, sold as a 7-oz bag. Chewy listed it at $24.99 in October 2026.

It is the strongest treat option here for a dog that has to avoid wheat. The BARK treats are built on whole wheat and spelt flour, and Merck lists wheat among the most common dog food allergens. A meat-jerky format avoids that biscuit base. Confirm the full ingredient list on the bag for grains before relying on it.

The tradeoff runs the other way for meat allergies. Beef and chicken are both on Merck's list of common dog allergens, and four proteins in one calendar is the opposite of single-protein treats. Skip this one for a dog that reacts to beef or chicken. For small dogs, break each piece smaller to keep the calories in check.

Frisco Holiday Countdown Plush Toy: best reusable no-treat calendar

From ChewyIn stock

Frisco Holiday Moveable Blocks Countdown Calendar Plush Squeaky Dog Toy, 3 count

A plush squeaky countdown toy with moveable blocks, so the countdown adds zero treat calories.

$14.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

This is a plush squeaky countdown toy with moveable blocks, sold as a 3 count, at $14.99 on Chewy in October 2026. Instead of opening a door, you move the blocks to count down the days, so the calendar is reusable from one December to the next.

It suits dogs on a weight plan, dogs on a strict diet, and households that would rather not add daily treats at all. A toy calendar adds no calories, so there is nothing to subtract from meals.

The tradeoff is durability. VCA notes that every dog has a different drive to destroy toys, and plush is built for gentle play. For a dog that shreds stuffed toys, keep this one for short play sessions you are watching, and VCA advises retiring any toy once stuffing starts to show.

Frisco Holiday Advent Calendar for Cats: best cat advent calendar

From ChewyIn stock

Frisco Holiday Advent Calendar for Cats, 12 count

Frisco's 12-toy holiday countdown for cats, with catnip and silvervine teaser toys.

$24.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

Frisco makes a cat version of its holiday advent calendar, sold as a 12 count and listed at $24.99 on Chewy in October 2026. It matches the small-dog calendar in count and price, which makes it easy to run both countdowns side by side.

It suits cats in a multi-pet home where the dog already has a calendar and the cat would otherwise be left out. Every door is a toy, so the countdown adds no treat calories.

The tradeoff is string and catnip. Chewy's listing describes silvervine-and-catnip plush toys with feather or ribbon teasers and a sisal ball with a feather tail. VCA warns that swallowed string or ribbon can become a linear foreign body, so keep the teaser toys for play sessions you are watching and put them away afterward. Space the catnip toys out rather than offering one every day.

Country Kitchen Holiday Dual Bites Cat Advent Calendar: best treats-only cat calendar

From ChewyIn stock

Country Kitchen Holiday Dual Bites Advent Calendar Crunchy Cat Treats, 4.3-oz box

A treats-only cat advent calendar of crunchy dual-bite treats in a 4.3-oz box.

$11.99

Buy on Chewy

Webvet may earn a commission when you click through to Chewy, at no extra cost to you.

This is the cat version of the Country Kitchen dual-bite calendar: crunchy cat treats in a 4.3-oz box, listed at $11.99 on Chewy in October 2026. It is the lower-priced of the two cat picks.

It suits cats that care more about food than toys, and homes that want to skip string and feather toys altogether. A treats-only box removes the toy question entirely.

The tradeoff is calories. VCA limits cat treats to 10 percent of daily calories, and a cat's daily total is small, so each door is a meaningful share. Check the calories per piece and the ingredient list on the box, and trim the cat's meals to make room.

Treat advent calendars vs toy advent calendars: which suits your dog

The practical difference is simple. A treat calendar adds calories every day; a toy calendar adds none. The Ontario Veterinary College recommends keeping any food outside a dog's daily meals to no more than 10 percent of its daily calories, and calendar treats fall squarely under that rule.

Toy calendars swap the calorie question for a size and durability question. VCA's chew toy guide says a toy should never be small enough to fit entirely in your dog's mouth. It adds that every dog has a different drive to destroy toys, so a plush countdown suits gentle players, not power chewers.

VCA also offers a quick fingernail test: a toy should be soft enough that you can indent it with a fingernail, so use it on every plush or rubber calendar toy. With those rules in mind, a treat calendar tends to suit:

• Dogs at a healthy weight with room in their treat allowance
• Food-motivated dogs that do not care much for toys
• Power chewers that would make short work of a plush toy
• Budget shoppers; the Country Kitchen Holiday Dual Bites Advent Calendar Crunchy Dog Treats, 6.7-oz box is the lowest-priced dog pick here

A toy calendar tends to suit:

• Dogs on a weight-loss plan or a strict veterinary diet
• Dogs with food allergies, since there is no ingredient list to worry about
• Gentle players that carry and cuddle toys rather than shred them
• Owners who want a reusable countdown, such as the Frisco Holiday Moveable Blocks Countdown Calendar Plush Squeaky Dog Toy, 3 count

Mixed calendars with toys and treats need both checks. Budget the treat calories, then size every toy against your dog's mouth. Other daily extras count too: if your dog already gets a chew from our vet recommended dog dental chews list, that chew comes out of the same 10 percent allowance as the calendar.

How to run an advent calendar without upsetting your dog's stomach

The fix for calendar treats is to make room for them, not to pile them on top of a full diet. The Ontario Veterinary College advises reducing the amount of food a dog is fed by 10 percent when treats are added, to allow for the treat calories.

There is no veterinary figure for how many calendar treats per day are safe. The limit is calorie-based, which is why one large biscuit and three tiny training-size pieces can land in very different places. Check the label for calories per piece and work from your dog's daily target.

The cap is not just about weight. The Veterinary Sciences review warns that letting snacks displace a complete and balanced diet may lead to deficiencies in essential nutrients. A calendar treat is a small extra, never a substitute for a meal.

A simple routine for the whole countdown:

1. Ask your vet for your dog's daily calorie target, or use the feeding amount you already know keeps your dog at a healthy weight.
2. Work out 10 percent of that number. That is the treat budget for the day, calendar door included.
3. Check the calories per piece on the calendar box and see how much of the budget one door uses.
4. Reduce the meal portion by about 10 percent on calendar days, as the Ontario Veterinary College suggests.
5. On day one, offer only a small piece of the new treat, as VCA recommends, and watch how your dog handles it.
6. Break larger treats into smaller pieces for small dogs, and spread one treat across the day if that suits your routine.
7. Count every other extra, including training treats, chews, and table scraps, against the same budget.

New foods are best introduced in small amounts, which is the reason for starting with a small piece. If a calendar treat disagrees with your dog, stop that treat rather than pushing through the rest of the doors, and switch to a toy-only countdown for the remaining days.

Holiday weeks bring plenty of other extras, so keep the calendar from becoming one more. Chewable supplements such as calming chews for dogs are food outside meals too, and belong in the daily allowance alongside the calendar.

Dog advent calendar safety: toy size, choking, and allergens

Dog toys advent calendar boxes and mixed calendars with toys and treats carry risks a treat-only box does not. VCA's chew toy guidance sets out the core rules for any dog toy advent calendar, whether it comes from BARK, a BarkBox-style subscription, a Costco shelf, or a boutique brand's Merry Barkmas box.

The first rule is construction. VCA says a dog's toy should have no ribbons, eyes, or other removable parts that can be easily swallowed or inhaled. Pull-test every calendar toy before handing it over, and remove any loose trim.

The second rule is size. A large dog toy advent calendar and a small dog toy advent calendar should not hold the same toys. A toy that suits a terrier can disappear into a retriever's mouth. If a calendar lists its toys as one size, as BARK's does, size every toy against your own dog.

The third rule is wear. VCA says to retire a toy when stuffing is showing, rope is frayed, or rubber is broken. Check calendar toys after each play session. BARK's manufacturer page carries no supervision wording, so do not rely on the label to tell you when to step in.

Reusable calendars, including wooden or fabric ones you refill each year, move the safety question to whatever you put inside. The same toy-size and treat-calorie rules apply. The same also holds for a cat toy advent calendar, covered in the cat section below.

Allergies are the other safety line. VCA's food allergy guidance says the most accurate diagnosis is a hypoallergenic diet trial of 8 to 12 weeks; Merck cites a minimum of 10 weeks. No other foods, treats, or supplements are fed during a trial, so a dog on one should skip treat calendars.

For dogs with a known allergy but no active trial, look for single-protein treats built on a protein your dog already tolerates. That is plain shorthand, not a VCA term; VCA describes a veterinary novel protein diet as one with nothing from the dog's previous foods. Read every ingredient, coatings and flavorings included.

Calendars are not the only seasonal hazard in the room. Our guide to Christmas plants toxic to pets covers the greenery that often sits right next to the advent calendar.

Cat advent calendars: what is different for cats

A cat advent calendar runs on the same calorie rule as a dog's. VCA's cat treat guidance says treats should be limited to 10 percent of a cat's daily calorie intake. Because that 10 percent is a slice of a much smaller total than most dogs eat, cat calendars need smaller pieces.

VCA also warns not to be fooled by treats labeled light or lower calorie, since they are not meaningfully lower for cats. A cat treat advent calendar needs the same label check as a dog box: calories per piece, then the ingredient list.

Catnip is the cat-specific reward that many calendars lean on. A 2017 study of sixty cats in Behavioural Processes found that all the cats responded, about 20 percent actively, such as rolling over, and about 80 percent passively. Other reporting linked to Cornell puts the share of non-responders at about half, so the sources do not agree.

Catnip is also not entirely harmless. The ASPCA lists it as toxic to cats, noting it can cause vomiting and diarrhea and that it sedates some cats while stimulating others. Treat catnip doors as an occasional thrill, not a daily dose, and space them out across the countdown.

Cat toys bring their own risk. VCA's holiday safety tips for cat owners warn that swallowed string or ribbon can form linear foreign bodies that become entangled in the intestinal tract. Points to keep in mind with any cat toy advent calendar:

• Let kittens play with string or ribbon toys only under your direct supervision, as VCA advises.
• Put feather and string wands away after each play session.
• If you see ribbon or tinsel coming from your cat's rear end, do not pull it; VCA says to see a vet.

The same caution applies to tinsel and ribbon on the tree itself. Our guide to a cat proof Christmas tree covers how to keep curious cats away from it.

A cat advent calendar from Costco, Amazon, or PetSmart deserves the same checks as our picks. A Hello Kitty or other character calendar may be made for people, not cats, so confirm it is a pet product. Split a dog and cat advent calendar sold as one box into separate countdowns, since the two need different piece sizes.

DIY dog advent calendar ideas

A homemade dog advent calendar gives you full control over piece size, ingredients, and calories, which makes it a strong option for dogs with allergies or small dogs with tight treat budgets. The trick is to fill it with foods your dog already tolerates, not new experiments.

How to make a dog advent calendar at home:

1. Pick a container with numbered spaces, such as a muffin tin, a row of small paper bags, or a reusable fabric or wooden calendar.
2. Number each space, choosing a 12-day or 24-day countdown.
3. Fill most spaces with pieces of a treat your dog already eats safely, or a portion of its regular kibble set aside from that day's meals.
4. Keep each piece as small as possible; VCA's puppy treat guidance recommends making treats as small as possible, which suits small dogs and puppies.
5. Swap some days for non-food rewards, such as a new walking route, a game of fetch, or a short training session.
6. Store the filled calendar out of your dog's reach so it cannot help itself to all 24 days at once.

Using kibble from the day's own ration is the simplest way to make your own dog advent calendar without adding calories. It keeps the daily total the same while the countdown still feels like a treat.

The ASPCA's list of people foods to avoid sets the hard limits for a DIY dog treat advent calendar:

• Chocolate: the darker the chocolate or the higher the caffeine content, the greater the toxicity risk
• Xylitol: found in sugar-free human treats, it can cause low blood sugar and potentially liver damage
• Grapes and raisins: can cause kidney damage in dogs
• Onion and garlic: the allium family can damage red blood cells and lead to anemia
• Macadamia nuts: listed by the ASPCA as harmful to dogs

If the calendar is part of a bigger holiday haul, our guides to Christmas gifts for dogs and the best dog water fountains cover presents that add nothing to the treat budget.
