You are looking at your dog at 10:30 pm on a Saturday, and something is not right. They are not acting normally. Something is different from how they were this morning. And you are standing in the hallway trying to decide whether to call the emergency veterinary clinic — which is forty minutes away and costs significantly more than a regular appointment — or whether to wait and call your regular vet first thing Monday morning.
This decision, made without the right information, costs dogs their lives every year. Not because owners do not care — they clearly care enough to be standing in the hallway at 10:30 pm, genuinely worried — but because they do not have a framework for distinguishing the serious from the serious-looking, the emergency from the urgent-but-not-immediately-life-threatening.
This guide provides that framework. Twelve symptoms that mean emergency care now. The signs that cannot wait and the explanation for why each one cannot wait. Save this before you need it. The night you need it is not the night to search for it.
Emergency Sign 1: Difficulty Breathing or Respiratory Distress
Any dog who is struggling to breathe — showing labored respiratory effort, breathing with their mouth open when they were not recently exercising, breathing with extended neck and elbows spread wide, breathing with audible wheezing or crackling sounds — is experiencing a respiratory emergency.
Dogs can die from respiratory distress in minutes. The causes range from allergic reaction and trauma to heart failure, fluid around the lungs, and tracheal collapse, and none of these can be assessed or treated at home. A dog who is visibly working to breathe needs oxygen and veterinary assessment immediately.
What you may see: Rapid, shallow breathing at rest. Open-mouth breathing without heat exposure or exercise. Extended neck posture. Blue or purple-tinged gums or tongue. Complete unwillingness to move.
What to do: Call the emergency clinic while loading the dog into the car. Keep the dog as calm and still as possible during transport.
Emergency Sign 2: Bloat or Suspected GDV
Gastric Dilatation-Volvulus — commonly called bloat or GDV — is one of the most rapidly fatal conditions in dogs. The stomach fills with gas and rotates on its axis, cutting off the blood supply. The time from symptom onset to death can be as little as one to two hours without treatment.
What you may see: A distended, drum-like abdomen that may be visibly swollen. Unproductive retching — the dog is trying to vomit and cannot. Extreme restlessness, the dog cannot find a comfortable position. Drooling and distress.
Who is most at risk: Large and giant breeds with deep chests — Great Danes, German Shepherds, Dobermans, Standard Poodles, Weimaraners, Retrievers. A dog of any size showing these symptoms warrants emergency assessment.
What to do: Do not wait to see if it resolves. This is the symptom most commonly described by owners of dogs who died as “I thought it was just an upset stomach.” Call the emergency clinic before you start the car.
Emergency Sign 3: Seizure — First Occurrence or Multiple in 24 Hours
A dog experiencing their first-ever seizure requires emergency assessment regardless of how quickly the seizure resolves. A dog who experiences more than one seizure in 24 hours — cluster seizures — requires emergency care even if each seizure resolves normally.
A seizure that lasts longer than five minutes (status epilepticus) is a life-threatening emergency requiring immediate intervention.
What you may see: Loss of consciousness, muscle rigidity, paddling legs, jaw snapping, urination or defecation without apparent awareness. A post-seizure phase of confusion, temporary blindness, or extreme fatigue that can last minutes to hours.
What to do during a seizure: Clear the area of objects that the dog could injure themselves on. Do not put your hands near the dog’s mouth. Time of the seizure — this information is important to the veterinarian. Call the emergency clinic.
What to do after: Do not assume a single resolved seizure means all is well. A first seizure requires investigation to determine the underlying cause.
Emergency Sign 4: Pale, White, Blue, or Yellow Gums
Normal dog gum color is pink — the specific shade of bubblegum. Any significant departure from this warrants immediate assessment.
Pale or white gums: Indicate reduced blood circulation or significant blood loss — from internal bleeding, severe shock, or anemia. This is an emergency.
Blue or purple gums: Indicate insufficient oxygenation — a respiratory or cardiac emergency. Get to the vet immediately.
Brick red gums: Can indicate early heat stroke or carbon monoxide exposure.
Yellow gums: Indicate jaundice, liver failure, or severe hemolytic anemia. Warrants emergency assessment.
How to check: Lift the lip and observe the gum color. Press your finger firmly against the gum for two seconds and release — the area should return to pink within two seconds (capillary refill time). A return that takes longer than two seconds indicates compromised circulation.
Emergency Sign 5: Suspected Poisoning or Toxic Ingestion
Any known or suspected ingestion of a toxic substance — xylitol, grapes or raisins, chocolate, rodenticide, medication, or any substance you cannot identify but know the dog has consumed — warrants immediate contact with either your emergency veterinarian or the ASPCA Animal Poison Control Center (888-426-4435, available 24/7).
Do not wait for symptoms to develop before calling. For many toxins — xylitol and rodenticide in particular — by the time clinical symptoms appear, organ damage has already occurred. Treatment is most effective when initiated before symptom onset, not after.
What to bring to the clinic: The packaging or a photograph of the label of whatever was consumed. An estimate of the quantity and the time of ingestion. Any vomit produced — it may contain diagnostic information.
What not to do: Do not induce vomiting without veterinary guidance. For some toxins, vomiting causes additional damage.
Emergency Sign 6: Inability to Urinate — Especially in Male Dogs
A dog who is attempting to urinate repeatedly and producing nothing — or producing very small amounts with visible straining and distress — may have a urinary obstruction. In male dogs, particularly, this is a life-threatening emergency that can cause kidney failure and bladder rupture within 24 hours if untreated.
What you may see: Repeated squatting or leg lifting without urination. Crying or whimpering during urination attempts. A distended, firm abdomen. Blood in the small amount of urine produced. General distress and restlessness.
The urgency: A complete urinary obstruction is fatal without treatment. If your dog has not urinated in 12+ hours and is showing signs of distress, this is not a wait-until-morning situation.
Emergency Sign 7: Suspected Broken Bone or Serious Trauma
Any dog who has been hit by a vehicle, fallen from a significant height, or been in a fight with another animal requires emergency veterinary assessment — regardless of whether obvious injury is visible.
Internal injuries — bleeding into the chest or abdomen — may not produce visible external signs for hours after the trauma event. A dog that was hit by a car and appears to be walking normally immediately after may have internal injuries that will become life-threatening over the next several hours without intervention.
The rule: Any significant trauma event warrants veterinary assessment the same day, even if the dog appears fine.
Emergency Sign 8: Eye Injury or Sudden Vision Changes
The eye is the most time-sensitive organ for injury — conditions that in other body systems might be urgent-but-not-emergency are emergencies in the eye because permanent vision loss can occur within hours of untreated injury or infection.
Emergency eye conditions: A prolapsed eye (the eye has come out of the socket — this occurs occasionally in brachycephalic breeds after trauma). Sudden clouding of one or both eyes. An eye that is significantly larger than the other, indicating acute glaucoma. Any visible penetrating injury to the eye surface.
What to do for a prolapsed eye: Keep the eye moist with saline solution or a wet cloth and get to the emergency clinic immediately. Do not attempt to push the eye back in. Time to treatment directly determines whether the eye can be saved.
Emergency Sign 9: Collapse or Sudden Inability to Stand
A dog who has collapsed and cannot rise, or who has suddenly lost the ability to use one or more limbs without prior injury, requires emergency assessment.
The causes of acute collapse in dogs include: heart arrhythmia, internal bleeding, severe hypoglycemia, neurological event, and extreme pain. None of these can be diagnosed or treated at home, and several can be fatal within hours without intervention.
What you may see: The dog falls and cannot get up. The dog is conscious but cannot control rear or front leg movement. The dog appears unaware of their surroundings. The dog loses consciousness.
Emergency Sign 10: Uncontrolled Bleeding
Wounds that are bleeding continuously for more than five minutes despite firm, direct pressure require emergency care. Arterial bleeding — blood that is bright red and pulsing rather than flowing steadily — is a particularly urgent emergency.
First aid while transporting: Apply direct, firm pressure with a clean cloth. Do not remove the cloth to check the wound — removing the pressure disrupts the clotting process. Add more material on top of the existing cloth if it saturates. Call ahead so the clinic can prepare for your arrival.
Emergency Sign 11: Suspected Spinal Injury
A dog who is dragging their rear legs, who has lost control of bladder or bowel function, or who cries out in pain when their back is touched may have a spinal injury or acute intervertebral disc disease.
The urgency of spinal emergencies: the window for surgical intervention that preserves neurological function is narrow — typically hours, not days. A dog showing signs of spinal injury who is assessed and treated within hours of symptom onset has significantly better outcomes than one who is assessed the following day.
Emergency Sign 12: Extreme Pain or Distress You Cannot Explain
Trust your knowledge of your dog. A dog who is in severe, unusual distress — pacing compulsively, crying or whimpering at rest, guarding a body part, unable to find a comfortable position, showing aggression when touched in an area where they are normally comfortable with contact — is communicating pain that warrants investigation.
You know your dog. If something is wrong in a way you cannot explain and the distress is severe, continuous, or escalating, the emergency clinic is the right call. Experienced emergency veterinarians consistently report that owner instinct is one of the more reliable diagnostic indicators available. If your gut is telling you this is serious, it is worth a phone call.
What to Do Before You Go
Call the emergency clinic before you arrive. Give them the dog’s age, breed, and symptoms. This allows them to prepare for your arrival and may allow them to give you guidance on first aid steps during transport.
Gather these things quickly: your regular vet’s records if accessible, a list of any medications the dog is currently taking, and any relevant history for the presenting symptom (when it started, whether it is getting worse).
