A veterinary emergency is a lousy time to start wondering whether you’re overreacting.
I’m quite happy to make the unnecessary phone call or arrive at the emergency clinic and be told we could’ve waited.
The other mistake — waiting when the dog actually needs help — is the one I don’t want to make.
This guide isn’t meant to diagnose your long-haired German Shepherd. It’s meant to help answer a much simpler question:
Do I watch this, call my veterinarian, or get in the car?
When there’s any doubt, call the veterinarian or emergency clinic and describe exactly what you’re seeing. They can help you decide what happens next.
First: Know Your Dog’s Normal
With rescue dogs, baseline matters because the dog standing in front of you today may not behave anything like the dog you’ll know six months from now.
Stress, travel, a new home, a food change and disrupted routines can all affect appetite, bowel movements, energy and behaviour.
That doesn’t mean we get to explain every physical change away as decompression.
Look for changes from that individual dog’s baseline:
- breathing differently
- moving differently
- refusing food or water
- vomiting repeatedly
- becoming unusually weak or quiet
- showing pain where there wasn’t pain before
- losing balance
- developing abdominal swelling
- behaving dramatically differently for no obvious reason
A single odd moment may mean very little. A meaningful change, a worsening pattern or several symptoms appearing together means more.
For the slower changes that don’t obviously belong in an emergency clinic, see our early health red flags for long-haired German Shepherds.
Emergency — Go Now
Some signs don’t belong in the “let’s see what happens” category.
Seek emergency veterinary care immediately for signs such as:
- difficulty breathing or obvious respiratory distress
- blue, grey, very pale or white gums
- collapse or loss of consciousness
- severe weakness or inability to stand
- a swollen, hard or painful abdomen, particularly with repeated attempts to vomit
- severe or uncontrolled bleeding
- major trauma such as being hit by a vehicle or a serious fall
- suspected poisoning or toxin ingestion
- heatstroke or severe overheating
- ongoing seizure activity lasting about five minutes or longer
- multiple seizures close together
- failure to recover normally after a seizure
- sudden paralysis or major neurological dysfunction
- severe allergic reaction, particularly facial swelling combined with breathing difficulty, vomiting, collapse or distress
- an obvious fracture, serious penetrating wound or severe eye injury
Veterinary emergency guidance consistently treats breathing difficulty, shock, collapse, poisoning, heatstroke, major trauma and ongoing seizures as conditions needing immediate assessment. Merck Veterinary Manual and VCA Animal Hospitals both provide useful overviews.
If you’re heading to emergency, call the clinic when you can do so safely. It gives the veterinary team some warning and may allow them to give you instructions for transport or immediate first aid.
Bloat and GDV: Know This One
If you live with a German Shepherd, gastric dilatation-volvulus — usually shortened to GDV and commonly called bloat — belongs on the list of emergencies you should recognize before you ever see it.
GDV happens when the stomach becomes distended and twists. It can interfere with blood circulation, damage the stomach and other organs, cause shock and become fatal without treatment.
Large, deep-chested dogs are at increased risk, and German Shepherds are among the breeds commonly affected.
Possible warning signs include:
- repeated attempts to vomit without producing anything
- swollen or tight abdomen
- restlessness or pacing
- excessive drooling
- panting
- abdominal pain
- pale gums
- weakness
- collapse
If you suspect GDV, you don’t wait to see whether it improves. You get to an emergency clinic.
Cornell University’s College of Veterinary Medicine describes GDV as life-threatening and requiring immediate medical and surgical intervention. Read Cornell’s GDV guidance.
Sudden Collapse: Don’t Watch and Wait
Collapse is one of those signs where I don’t think we need to get clever. A dog that suddenly collapses needs veterinary assessment.
There are many possible causes, including internal bleeding, cardiac problems, shock, neurological disease, severe metabolic problems, poisoning, heatstroke and trauma. You can’t reliably sort those possibilities out from the living room.
VCA specifically advises that collapse should always be treated as a medical emergency, so call the emergency clinic and go.
Hemangiosarcoma and Internal Bleeding
German Shepherds are among the breeds in which hemangiosarcoma occurs more commonly. It’s an aggressive cancer arising from blood vessels, and tumours involving organs such as the spleen or heart can rupture and cause serious internal bleeding.
Cornell lists possible emergency signs from rupture or bleeding including:
- sudden collapse
- severe weakness
- rapid or difficult breathing
- pale gums
Other splenic masses can bleed too, so those signs don’t prove a dog has hemangiosarcoma. That diagnosis requires veterinary investigation.
What they do tell you is that the dog may be in serious trouble and needs emergency assessment.

Seizures: What Changes the Urgency?
Watching a dog have a seizure is frightening. The first job is keeping the dog safe, not trying to restrain them.
Move nearby objects out of the way if you can do so safely. Keep your hands away from the dog’s mouth. Dogs don’t swallow their tongues during seizures.
Time the seizure.
Seek emergency treatment when:
- seizure activity continues for about five minutes or longer
- several seizures occur close together
- another seizure begins before your dog has properly recovered
- your dog doesn’t return toward normal consciousness after the seizure
- there are other serious signs such as poisoning, trauma, breathing trouble or collapse
A first seizure still warrants veterinary evaluation even when it stops quickly and the dog recovers. Call your veterinarian and tell them exactly what happened.
Vomiting, Diarrhea and Not Eating
Rigid internet timelines can get people into trouble here.
One loose stool in an otherwise normal dog isn’t the same situation as repeated vomiting in a dog who has become weak and stopped drinking.
Call a veterinarian promptly when vomiting or diarrhea is repeated, worsening, bloody, accompanied by pain, combined with marked lethargy or weakness, or preventing your dog from keeping water down.
Black, tarry stool can indicate digested blood and deserves veterinary attention.
Loss of appetite shouldn’t simply be written off for two or three days because the dog is new, nervous or “probably stressed.” VCA’s urgent-care guidance, for example, recommends prompt evaluation for appetite loss and uses more than 12 hours without eating as one reason for urgent assessment.
Age, existing disease, medications and everything else happening with the dog matter, so call and let the veterinarian decide how quickly they want to see them.
Sudden Lameness and Severe Pain
Not every limp requires an emergency hospital.
But severe pain, major trauma, an obvious deformity, a suspected fracture, uncontrolled bleeding or a dog that suddenly can’t use a limb normally needs prompt veterinary assessment.
For a mild limp in a dog who’s otherwise comfortable, call your regular veterinarian and describe what happened.
And don’t start reaching into the human medicine cabinet. Common human pain medications can be dangerous to dogs unless a veterinarian specifically directs their use.
Suspected Poisoning: Call Before You Experiment
If your dog may have swallowed a medication, chemical, toxic food, plant or other potentially poisonous substance, contact a veterinarian or veterinary poison service immediately.
If there’s packaging, take it with you or photograph the label.
Don’t induce vomiting unless a veterinarian or veterinary poison professional tells you to. Whether vomiting is appropriate depends on what was swallowed and the condition of the dog.
Before the Emergency Happens
Emergency preparation isn’t glamorous, but it’s worth doing before you need it.
Every Shepherd household should know:
- where the nearest veterinary emergency hospital is
- whether it actually operates 24 hours a day
- the emergency clinic’s current phone number
- how long the drive normally takes
- where the dog’s medical records and medication list are stored
- the dog’s current medications and doses
- the dog’s approximate current weight
- how you’ll physically move an injured 70-, 80- or 90-pound Shepherd if they cannot walk
- where your pet insurance information is kept, if you have insurance
Check the emergency hospital occasionally too. Clinics close, hours change and emergency services get reduced. The hospital you used three years ago may not be the hospital available at two in the morning now.
That’s particularly worth remembering in Canada, where emergency veterinary availability varies by community.
When You Call the Vet
Give them useful information:
- what happened
- when it started
- whether it’s getting worse
- what your dog is doing right now
- gum colour if you can check safely
- whether the dog can stand and walk
- whether they’re breathing normally
- vomiting, diarrhea, bleeding or seizure activity
- known medications or medical conditions
- anything the dog may have eaten or swallowed
You don’t need to figure out the diagnosis before you call. Tell the veterinary team what happened and what you’re seeing now. They’ll decide what information matters next.
If your Shepherd already has a complicated medical history, keep the important information somewhere you can actually find it under pressure — diagnoses, medications, doses, recent test results and anything else your veterinarian may need quickly.
The Rule I’d Use
If something has changed enough that you’re seriously wondering whether your dog needs veterinary help, make the call.
You may be told to monitor, and that’s fine. Now you’re monitoring because a veterinary professional has heard what’s happening and thinks that’s reasonable — not because you were afraid of looking foolish.
