If you are asking whether your dog is depressed, you have probably noticed a change: less interest in play, more sleep, a plate left half full. The most common signs are a drop in interest in favorite activities, reduced appetite, low energy, and either withdrawal or unusual clinginess, according to the American Kennel Club. The harder part is the second question: is it sadness, or is it pain or illness wearing a sad face? This guide covers both, and shows you how to tell your vet what you have seen.
TL;DR
- Typical signs of a depressed dog are lost interest in play and walks, lower appetite, low energy, changed sleep, hiding, or clinginess.
- “Depression” in dogs is a description of mood and behavior, not a formal diagnosis, and the same signs often come from pain or disease.
- A vet visit comes first. Depression is usually a diagnosis of exclusion, so physical causes have to be ruled out.
- Triggers include a death, a move, a new schedule, boredom, and long-running stress. Notes and videos of what changed help your vet.
- Tracking eating, sleeping, walking, and play against your own dog’s normal makes slow drift easier to catch.

Can dogs actually get depressed?
Probably, in some form, though nobody can say how closely a dog’s experience matches a human’s. A veterinary review in the American Animal Hospital Association’s magazine says that animals likely suffer from some type of depression, while noting how hard it is to judge how similar the emotional state is to ours. The same article notes that chronic stress can cause atrophy in the hippocampus, which affects learning and cognitive function. So prolonged low mood is not something to wave away as a phase.
There is also a plain-language caveat worth keeping in mind. PetMD describes dog depression as a noticeable change in mood and behavior, not a formal medical diagnosis. You are not diagnosing a condition at home. You are noticing that your dog is behaving unlike themselves and working out why.
The signs of dog depression
No single sign proves anything. What matters is a cluster of changes that are new for your dog and that last. Here are the ones veterinary sources list most often.
Appetite changes
Reduced appetite is on nearly every list, including the AKC’s. Watch for details: Does your dog skip meals but still take treats? Eat only when you hand-feed? Eat much faster or slower than usual? Appetite changes are also among the most common first signs of a physical problem, which is why we wrote a separate guide on why a dog eats less and what the red flags are.
Low energy and lost interest
A dog who used to bring the leash and now watches from the couch is showing what vets call decreased interest in favorite activities. Lethargy goes with it. Look for:
- Ignoring toys that were once favorites
- Shorter, slower walks, or reluctance to leave the house
- Less excitement at your arrival, mealtimes, or the car
Sleep changes
Sleeping much more is the classic sign, but restless nights or an inability to settle can matter just as much. The Kennel Club lists an inability to settle among the signs of an unhappy dog. A dog who suddenly naps in a different room, or never fully relaxes, is telling you something.
Social changes: withdrawal or clinginess
Both directions count. Some dogs hide, avoid the family, or stop greeting visitors. Others shadow you from room to room and cannot be left alone. The AKC includes both increased clinginess and withdrawal on its list. What matters is the contrast with your dog’s usual style.
Body language and sounds
PetMD lists sad or droopy eyes, ears pulled back, whimpering, howling, and restlessness among the other symptoms. A flat, lowered posture and a tail that stays down are worth noting too, though these are easy to over-read in individual dogs, since some breeds simply have droopy faces.
Self-soothing and “acting out” behavior
Excessive licking or chewing can be a sign of low mood, according to a UK veterinary practice’s symptom guide. The Kennel Club adds that unhappy dogs may chew, try to escape, become more reactive, lose toilet training, or become aggressive. If your adult, house-trained dog starts having accidents, do not assume it is spite or sadness. Urinary and digestive problems are far more likely and need a vet.
What else can look like depression
This is the part many articles gloss over. The AKC says that when a dog slows down or becomes reluctant to engage without any life-changing event, a medical or pain-related issue is the likelier explanation. Texas A&M’s Dr. Ashley Navarrette, speaking in 2022, described depression as often a diagnosis of exclusion: the vet has to rule out medical causes first. The Merck Veterinary Manual says the same about behavior problems in general, that veterinarians must first exclude medical problems that may cause or contribute to the signs.
Here is how some common look-alikes differ in practice. These are patterns to bring to your vet, not a way to diagnose at home.
| What you see | Could be low mood if… | Could be medical if… |
|---|---|---|
| Sleeping more | It followed a loss or big routine change | It came on slowly in an older dog, or with stiffness getting up |
| Not eating | Your dog still shows interest in treats and food from your hand | Vomiting, diarrhea, drooling, or weight loss come with it |
| Hiding or avoiding touch | Something changed at home | Your dog flinches when touched in particular spots |
| Refusing walks | Your dog seems fearful or flat outdoors | Limping, slow stairs, or trouble jumping |
| Restlessness at night | A schedule or household change occurred | Panting, pacing, or confusion, especially in a senior dog |
If your senior dog seems vacant, lost in familiar rooms, or awake at night, read our guide to canine cognitive dysfunction signs. It can resemble depression closely. Likewise, a dog with ongoing soft stool and low energy may have a parasite rather than a mood problem; our Giardia guide explains symptoms and when to call the vet.
Anxiety is another overlap. Fear, stress, and low mood share many outward signs, and a dog can have more than one at once. A vet or a veterinary behaviorist is the person to sort that out.
What can trigger depression-like behavior
The AKC names chronic pain, environmental changes, loss of an owner or companion, lack of stimulation, and prolonged stress or anxiety as causes. PetMD adds underlying disease, moving homes, a death in the family, and changes to work schedules. Dr. Navarrette ties depression in pets mainly to significant life changes, such as bereavement or sudden changes in routine.
In practice, ask yourself what changed in the last few weeks:
- Loss. A housemate dog, a cat, or a person who has moved out or died.
- Routine. You went back to the office, started a night shift, or changed walk times. The Kennel Club notes that changes in routine, environment, or social group can affect a dog’s mood as they adjust.
- Environment. A move, renovation, new baby, new pet, or visitors staying.
- Boredom. The Kennel Club says boredom can lead to behavioral problems, including depression, especially in working dogs. A border collie on a thirty-minute walk may be in trouble even if a basset hound is not.
- Pain or illness. Often the hidden driver, especially in middle-aged and older dogs.
Most dogs adjust to change within a short time. If the change in behavior sticks around, treat it as a health question.
When to see a veterinarian
The short answer: sooner than you think, and the same day in some cases.
PetMD advises a vet visit if your dog suddenly becomes withdrawn or seems unlike themselves. It also says to seek emergency care if your dog stops eating, vomits, shows destructive behavior, or is extremely lethargic. It adds that dog depression is not a medical emergency, but should never be ignored. A UK veterinary practice suggests a visit when behavior changes last more than a few days, or when appetite, drinking, sleep, or energy change. Dogs Trust, a UK charity, also recommends veterinary advice for recent behavior changes, fear, anxiety, withdrawal, or low mood.
Call right away for vomiting, diarrhea, weight loss, or signs of pain. Do not wait to see whether it passes.
What to bring to the appointment
Dogs Trust suggests bringing videos, diaries, or notes so the vet can assess behavior. Dogs often act normal in the exam room, so your records matter. Aim to have:
- A timeline. When you first noticed the change, and whether it is getting better or worse.
- Household changes. Moves, schedule shifts, losses, new animals, visitors.
- Specifics on eating, drinking, sleeping, and bathroom habits. Numbers beat impressions: how many hours asleep, how much food left over, how many walks skipped.
- Short videos. Limping, restlessness, repetitive licking, or an odd posture.
- A list of medications, supplements, and recent diet changes.
If weight has changed, mention that too. Our guide on dog weight gain and body condition scoring explains how to track it.
How to support your dog while you get answers
The vet visit comes first. After that, and alongside whatever plan your vet gives you, the sensible basics are things most owners can do without risk:
- Keep the routine steady. Feed, walk, and go out at consistent times. Predictability is calming.
- Add gentle activity. Extra sniffing walks, a new route, a puzzle feeder, or short training games. If your vet has found pain, follow their guidance on how much exercise is right.
- Spend quality time together. Sit with your dog, brush them, or play whatever game they still enjoy.
- Reward the behavior you want. Praise and treat engagement, however small, instead of scolding withdrawal.
- Do not force it. A dog who hides may need a quiet spot and a little time rather than pressure.
If the cause is a loss, a new schedule, or boredom, these steps often matter most. If the cause is medical, they are support, not treatment. Ask your vet whether a referral to a veterinary behaviorist makes sense for lasting problems. Do not start medications or supplements for mood without veterinary direction.
Perspective: why we think “normal for your dog” beats any checklist
Checklists of depression signs are useful, but they have a built-in problem: they describe an average dog. Your dog is not average. A Labrador who sleeps eighteen hours a day may be perfectly content, while a terrier who sleeps ten may be unwell. Nobody, including a vet who sees your dog once or twice a year, knows your dog’s baseline the way you do, and even you cannot recall exactly how many meals were finished three weeks ago.
That is why we built Fudini around a dog’s own routine rather than around GPS or raw activity numbers. The collar learns how your dog normally eats, sleeps, walks, and plays over several weeks, then alerts you only when behavior drifts from that baseline in a meaningful way. The idea is not to diagnose sadness. It is to catch the slow, quiet change that is easy to miss day to day, and to give you something concrete to bring to the vet instead of a feeling that “something is off.”
We are also careful about what we do not claim. A behavior alert cannot tell you whether your dog is depressed, in pain, anxious, or coming down with something. It tells you the pattern has changed, and a veterinarian does the rest. We document how we build it in the open, including how we taught a model to recognize eating, and our guides are free and carry no sponsored product pushes.

Tracking your dog’s baseline with Fudini
If your dog’s mood or habits worry you, the most useful thing you can have is a record of what normal looks like and when it shifted. The Fudini App is an iOS app that works with our sensor collar to track eating, sleeping, walking, and playing, learn your dog’s routine, and flag meaningful drift without flooding you with raw data. It also includes weight tracking and wellness tracking, which help when you put together a timeline for your vet. The app has no published price at the moment.
You can see how the whole system works on the Fudini homepage, or browse our free dog health and behavior articles whether or not you ever use the collar.
Is it depression or a normal off day?
Every dog has slow days: after a vet visit, in hot weather, after a long weekend of hiking. A single day is rarely a worry. These patterns deserve more attention:
- The change has lasted more than a few days.
- More than one area has shifted at once, say appetite and sleep and play.
- It followed a clear trigger, or came with no explanation at all.
- Your dog is older, and slowing down is being put down to age. Age is not a diagnosis, and pain often hides behind it.
When in doubt, call your vet’s office and describe what you see. Staff can tell you whether it can wait for a regular appointment.
FAQ
How do I know if my dog is depressed or just tired?
Tired dogs bounce back after rest and still show interest in food, play, and you. A dog with a deeper problem stays flat for days, loses interest in favorite things, and may change eating and sleeping habits. Because pain and illness can look identical, a vet check is the reliable way to tell the difference.
Can a dog get depressed after losing another pet or owner?
Yes, bereavement is one of the most commonly named triggers. Texas A&M’s veterinary college links pet depression mainly to big life changes such as a death or sudden routine shifts. Keep the routine steady, give extra attention, and tell your vet if appetite or energy stays low.
Do dogs get depressed in winter?
Some owners report a seasonal dip, and the Kennel Club discusses canine seasonal affective disorder alongside dog depression. Shorter days also mean shorter walks, which can cause boredom and low energy on their own. Keep exercise and enrichment up, and see your vet if the change is more than mild.
Is dog depression an emergency?
Not by itself. PetMD says it is not a medical emergency but should never be ignored. Treat it as urgent if your dog stops eating, vomits, has diarrhea, seems in pain, or is extremely lethargic, since those point to physical illness.
