Every dog owner has had that moment: your dog does something unusual and you immediately wonder, “Do I need to call the vet?”
Sometimes the answer is obvious. A serious injury or difficulty breathing needs immediate attention. But many situations aren’t so clear. Maybe your dog skipped breakfast, vomited once, seems more tired than usual, or suddenly started drinking more water.
Knowing which symptoms can wait and which ones shouldn’t can help you make better decisions for your dog.
When Does a Dog Need Emergency Veterinary Care?
Some symptoms should not wait for a regular appointment.
Contact a veterinarian or emergency veterinary clinic immediately if your dog has:
- Difficulty breathing or severe shortness of breath
- Collapsed or lost consciousness
- Uncontrolled bleeding
- Severe trauma, such as being hit by a vehicle
- Repeated seizures or a seizure lasting several minutes
- A swollen or suddenly enlarged abdomen, especially with unsuccessful attempts to vomit
- Suspected poisoning
- Severe weakness or inability to stand
- Pale, blue, gray, or unusually white gums
- Signs of heatstroke
- Severe pain
- Choking or difficulty swallowing
- Inability to urinate
When you’re unsure whether something is an emergency, calling a veterinary clinic is usually the safest option. They can help determine how urgently your dog needs to be examined.
When Should You Make a Regular Vet Appointment?
Not every problem requires an emergency visit, but persistent changes shouldn’t be ignored.
Consider scheduling an appointment if your dog develops symptoms such as:
- Ongoing vomiting or diarrhea
- Changes in appetite
- Unexplained weight loss or weight gain
- Persistent coughing
- Frequent scratching or skin problems
- Limping that doesn’t improve
- Bad breath or difficulty eating
- Changes in behavior
- Unusual tiredness
- Increased thirst or urination
- New lumps or bumps
- Changes in bathroom habits
One mild symptom for a short period may not always indicate something serious. But symptoms that continue, worsen, or occur together deserve veterinary attention.
What If Your Dog Is Drinking More Water Than Usual?
Dogs naturally drink more after exercise, during hot weather, or after eating certain foods.
However, a noticeable and persistent increase in thirst can sometimes be associated with an underlying medical problem.
If you’re suddenly refilling the water bowl much more often than usual—or your dog is also urinating more frequently—it’s worth paying attention.

Never intentionally restrict your dog’s access to fresh water unless your veterinarian specifically instructs you to do so.
What If Your Dog Is Coughing?
An occasional cough doesn’t necessarily mean something is seriously wrong.
Dogs may cough after drinking quickly, pulling against a collar, or because something briefly irritated their throat.
However, frequent or persistent coughing should be discussed with a veterinarian, particularly if your dog also seems tired, has difficulty breathing, isn’t eating normally, or the cough is becoming worse.
Our guide Why Does My Dog Cough? explains some of the common reasons behind canine coughing.
What About Vomiting and Diarrhea?
Dogs occasionally experience mild digestive upset.
A single episode of vomiting in an otherwise bright, active adult dog isn’t always an emergency. But repeated vomiting or diarrhea can quickly lead to dehydration and may indicate something more serious.
Contact your veterinarian sooner if:
- Vomiting happens repeatedly
- There’s blood in vomit or stool
- Your dog seems weak or painful
- Your dog cannot keep water down
- The abdomen appears swollen
- You suspect your dog swallowed something dangerous
- The dog is very young, elderly, or has an existing health condition
Puppies can become dehydrated much faster than healthy adult dogs, so it’s especially important to monitor them closely.
Should You Take Your Dog to the Vet for Itching?
An occasional scratch is completely normal.
Constant scratching isn’t.
Persistent itching can have many possible causes, including fleas, environmental allergies, food sensitivities, dry skin, infections, and other skin conditions.
Watch for redness, hair loss, sores, unusual odors, frequent paw licking, or repeated ear problems.
If your dog can’t seem to stop scratching, see Why Is My Dog Itching So Much? for more information about common causes.
What If Your Dog Suddenly Stops Eating?
Dogs occasionally skip a meal, particularly after eating extra treats, experiencing a change in routine, or having an unusually quiet day.
But a significant change in appetite deserves attention.
Contact your veterinarian if your dog refuses food for an extended period or if loss of appetite occurs together with symptoms such as vomiting, diarrhea, weakness, pain, bloating, or unusual behavior.
Puppies, senior dogs, and dogs with existing medical conditions may need veterinary attention sooner.
Is Sleeping More Than Usual a Reason to Visit the Vet?
Dogs sleep a surprising amount.
Most adult dogs spend roughly 12–14 hours a day sleeping, while puppies and senior dogs may sleep considerably more.
That’s why the number of hours alone isn’t necessarily concerning.
What matters is whether something has changed.
If your normally energetic dog suddenly spends most of the day sleeping, doesn’t want to walk or play, seems difficult to wake, or has other symptoms, contact your veterinarian.

What If Your Dog Is Shaking?
Dogs shake for many reasons.
They may be cold, frightened, excited, stressed, or simply shaking water from their coat. But shaking can also occur when a dog is experiencing pain or illness.
If the shaking is unexplained, persistent, severe, or accompanied by weakness, vomiting, difficulty walking, breathing problems, or other unusual symptoms, seek veterinary advice.

Pay Attention to Changes in Your Dog’s Normal Behavior
One of the most useful things you can do is learn what’s normal for your dog.
You know how excited they usually are about breakfast.
You know how much they normally drink.
You know whether they race toward the door when it’s time for a walk or would rather stay on the couch.
When those everyday behaviors suddenly change, it’s worth paying attention.
A single unusual behavior may mean very little. Several changes happening together can be much more significant.
How Often Should Healthy Dogs Visit the Vet?
Veterinary care isn’t only for when your dog is sick.
Regular wellness examinations can help identify potential problems before obvious symptoms appear.
As a general guideline, healthy adult dogs should usually have a veterinary wellness examination at least once a year.
Puppies need several visits during their first year for vaccinations, growth monitoring, parasite prevention, and other preventive care.
Senior dogs may benefit from more frequent checkups—often every six months—depending on their age and health.
Your veterinarian can recommend an appropriate schedule for your individual dog.
What Information Should You Give Your Vet?
When you call or visit the veterinarian, specific information can be extremely helpful.
Try to note:
- When the symptoms started
- How often they’re happening
- Whether they’re getting worse
- Changes in eating or drinking
- Changes in urination or bowel movements
- Any medications or supplements your dog takes
- Anything unusual your dog may have eaten
- Recent travel or environmental changes
Photos or short videos can also be useful for symptoms that don’t happen continuously, such as coughing, shaking, limping, or unusual behavior.
Trust Your Instincts
You don’t need to diagnose your dog yourself.
That’s your veterinarian’s job.
Your role is simply to notice when something seems different and decide whether professional advice is needed.
If your dog seems seriously ill, is rapidly getting worse, or you’re worried something isn’t right, it’s better to contact a veterinarian than wait for a symptom to become severe.
FAQ
Should I take my dog to the vet if they’re acting strange?
A temporary change in behavior isn’t always an emergency, but sudden or persistent behavioral changes can sometimes indicate pain, illness, fear, or another problem. Contact your veterinarian if the behavior is significant, continues, or occurs with physical symptoms.
How do I know if my dog is in pain?
Possible signs include limping, trembling, panting, restlessness, reluctance to move, unusual aggression, hiding, whining, changes in appetite, or reacting when a particular area is touched.
Should I call the vet before going to an emergency clinic?
If possible, yes. Calling ahead allows the clinic to advise you and prepare for your arrival. However, don’t delay urgent care when your dog is experiencing a life-threatening emergency.
Is it okay to wait and see if my dog gets better?
For mild, isolated symptoms in an otherwise healthy dog, monitoring may sometimes be appropriate. But severe, persistent, worsening, or multiple symptoms should be discussed with a veterinarian.
Final Thoughts
Knowing when to take your dog to the vet isn’t always easy.
Minor changes sometimes resolve on their own, while seemingly small symptoms can occasionally be the first sign that something more serious is happening.
The best approach is to pay attention to changes from your dog’s normal behavior, especially when symptoms persist, worsen, or appear together.
And when you’re uncertain, call your veterinarian. You don’t have to wait until you’re completely sure something is wrong before asking for professional advice.
