Do Dogs and Cats Get the Winter Blues?

Many dogs and cats do seem to change in winter, sleeping more, playing less, and acting clingier or restless, even though veterinarians disagree about whether it is true seasonal affective disorder (SAD). A survey by the UK veterinary charity PDSA found that about one in three dog owners saw their dog’s mood dip in the colder months. The likely causes are less daylight, shorter and rushed outings, cold, stiff joints, and pets picking up on their owners’ low energy. The best fixes are simple: get your pet outside around midday, put their bed near a bright window, add indoor brain games, and keep a steady routine. If the change is sudden or severe, call your veterinarian.

In Colorado, the clocks fell back on November 1, and sunset now arrives before 5 p.m. in the Denver area. That means fewer daylight hours for your pet to use, and now is the time to plan around it.

What Are Pet Winter Blues, and What Does the Research Say?

Pet winter blues is an informal term for the drop in energy, mood, and playfulness that many owners notice in dogs and cats once days get short and cold. Pets cannot tell us how they feel, so owners and veterinarians work from what they can see: changes in sleep, appetite, activity, and behavior.

The evidence is thinner than the headlines suggest, and it helps to be clear about that. The most-quoted figure comes from a PDSA survey, which found that roughly one in three dog owners noticed their dog’s mood fall during the winter months. Other owner surveys point the same way. A New Zealand pet insurer found that about one in three cat owners said their cat seemed less playful in winter. These are owner reports, not clinical diagnoses.

Veterinary experts are cautious. The American Kennel Club’s chief veterinary officer has said there is no scientific evidence yet that dogs get SAD the way people do. Dogs do have a pineal gland that makes melatonin, and one study of sled dogs found higher melatonin in winter than summer, so a seasonal link is plausible. Their honest conclusion is that seasonal mood and behavior changes in pets are real enough to notice, and the cause is probably a mix of biology, routine, and environment rather than one condition.

Whatever the label, it is worth acting on. Mood and behavior changes in your pet deserve attention even when the cause is unclear.

What Causes Winter Slumps in Dogs and Cats?

Four things usually combine: less daylight, less stimulation, a mirrored owner mood, and cold-aggravated aches.

1. Light and body chemistry. Melatonin, the sleep hormone, rises in the dark, while serotonin, which supports mood, depends on sunlight. With fewer daylight hours, pets may make more melatonin and less serotonin, which can leave them sleepy and flat.
2. Under-stimulation. Winter walks get shorter and more rushed, sniffing time shrinks, and dogs see fewer neighborhood friends. A dog that loses hours of exercise and scent work can turn restless, mope, or start chewing. Owner surveys back this up: nearly half of dog owners said their dogs exercise less in cold weather.
3. Mirroring you. Dogs and cats read body language, tone, and routine closely. If cold weather has you on the couch more often, or you feel the winter blues yourself, your pet may slow down to match.
4. Cold and stiff joints. Cold weather can worsen arthritis in older pets. A dog that balks at a walk or a cat that stops jumping up may not be sad at all. They may simply hurt.

What Are the Signs of Winter Blues in Dogs and Cats?

The most common sign is a change from your pet’s normal self that shows up as the days shorten and lasts for weeks. Look for:

• Sleeping noticeably more hours a day
• Reluctance to get up for morning walks or to play with favorite toys
• Clinginess, or the opposite: hiding or isolating in quiet corners
• Appetite changes, either begging for extra food and treats or mild disinterest in meals
• Whining, restlessness, or minor destructive behavior from pent-up energy

Cats tend to show it more quietly. A cat may groom less, play less, spend more time hidden, or sleep in a new spot. Because cats hide discomfort well, a subtle change is worth noticing early.

One caution on food. Some owners respond to a gloomy pet with extra treats, and winter weight gain is a real risk when activity drops. Comfort snacks can help the mood for a minute and hurt the waistline for months.

How Can I Help My Pet Beat the Winter Blues?

Give your pet more light, more mental work, and a steadier routine. These steps work for most dogs and cats.

1. Chase midday sunlight. Move the main walk to the brightest part of the day, around noon, instead of relying on dark mornings and evenings. Colorado’s winter sun can be strong even when it’s cold, so a coat on a short-haired dog beats skipping the walk.
2. Open the blinds. Put dog and cat beds near large south- or west-facing windows so they can soak up whatever natural light is available.
3. Ramp up indoor brain games. Mental work tires dogs as much as physical work. Try snuffle mats, puzzle feeders, treat hide-and-seek, or five-minute trick-training sessions. For cats, add window perches, a food puzzle, or short wand-toy play sessions.
4. Keep the routine. Pets do best when feeding, walks, and play happen at consistent times, even as the seasons shift. This matters extra right after the time change, when the clock says one thing and your pet’s body says another.
5. Keep them moving, gently. Several short outings beat one skipped walk. For senior pets, warm bedding and low-impact activity can ease cold-stiff joints.
6. Check your own energy. Because pets mirror us, a daily walk or play session can lift you both.

One note on supplements: don’t give a pet vitamin D to fight the winter blues. Excess vitamin D can be dangerous, so use it only if your veterinarian prescribes it.

When Is It Not the Winter Blues?

Call your veterinarian if your pet shows sudden or severe lethargy, stops eating completely, or seems to be in pain. Thyroid disorders, kidney disease, and arthritis can all look like a seasonal mood dip, and so can many other medical problems. Seasonal blues should ease once your pet gets more light, activity, and routine. A change that is abrupt, severe, or not improving after a few weeks needs a professional look. When you are unsure, call and describe what you are seeing.

How Doggie Dude Ranch and the O’Cat Corral Help Pets Through the Short Days

A boarding stay can be a break from the winter slump, because the day is built around activity, routine, and attention.

For dogs, the schedule at our dog boarding and daycare program is predictable from morning to night: a morning break outside at 7:00, breakfast at 7:30, rest, then supervised playtime from 10:30 to 12:30. That playtime falls in the brightest part of the day, right when the advice for beating the winter blues says to get outside. After afternoon naps come another outdoor break, dinner, and a last potty break in the evening. Dogs get the social play and sniffing time that winter often squeezes out at home.

Winter comfort is part of the plan too. Small dogs come inside to play in our climate-controlled playroom, short-haired dogs wear jackets during outdoor play, and long-haired dogs are towel-dried and blow-dried after playing in the snow, so cold and wet never cut the fun short.

Cats at the O’Cat Corral stay indoors in quiet condos away from the dogs, with daily staff interaction. A cat that is withdrawn at home still gets regular, gentle attention from people who learn what is normal for that cat.

Because pets show winter changes in small ways, observation matters. Our staff see your pet every day of a stay and notice shifts in appetite, energy, and mood, then pass along anything unusual so you can follow up with your veterinarian. We post photos of our guests on our Facebook page, so you can see for yourself how your pet is doing.

If your dog or cat is boarding with us for the holidays, our boarding prep page explains how to get your pet ready for a stay.

Winter Blues in Pets: Quick Answers

Do dogs and cats get seasonal depression? Many owners report mood and energy dips in winter, and a PDSA survey found about one in three dog owners saw one. Veterinarians say there is no proof yet that pets get SAD exactly as people do, but the behavior changes are real and worth addressing.

Why is my dog sleeping more in winter? Less daylight can raise melatonin, and shorter, colder days mean less activity. Some extra rest is normal. Call your veterinarian if the sleepiness is sudden, severe, or paired with a lost appetite or signs of pain.

Can cats get the winter blues? Cats can show similar changes, like playing less, hiding more, or grooming less. Researchers do not know for certain that cats get true seasonal depression, so rule out medical causes such as arthritis first.

How can I cheer up my pet in winter? Get them outside around midday, move their bed near a bright window, add puzzle feeders and short training games, and keep feeding and play at consistent times.

Does the end of daylight saving time affect pets? Pets don’t read clocks, but their routines do. After the clocks fall back, meals and walks land an hour off from their body clock, and dusk arrives earlier. Keep the routine steady, and if your pet struggles, shift meal and walk times by 10 to 15 minutes every few days.

When should I see a veterinarian? See one if your pet is suddenly very lethargic, refuses food, seems painful, or if a mood change has not improved after a few weeks of more light and activity.

Getting Through the Short Days Together

Winter slumps in pets are common, usually mild, and often fixable with light, activity, and routine. Watch for changes from your pet’s normal self, rule out medical causes when something seems off, and use the midday hours well while they last.
