Dog Symptom Guide: Emergency Signs, Urgent Problems, and Monitoring
This dog symptom guide is designed for the moment when something has changed and the owner needs a triage path. It explains which signs mean emergency care now, which deserve a same-day call, and which details help a veterinarian understand whether the problem is getting better or worse.
Practical symptom triage signals
- Breathing trouble, pale gums, collapse, repeated seizures, suspected poisoning, bloat signs, and inability to urinate are emergency-level signs.
- Vomiting, diarrhea, coughing, lameness, skin swelling, ear pain, appetite loss, and increased drinking become more concerning when paired with lethargy, pain, blood, fever, or dehydration.
- A useful call to the vet includes timeline, food and water intake, medication access, stool and urine changes, pain behavior, and a short video when movement or breathing looks abnormal.
- Normal behavior does not rule out risk after toxin exposure, bloat signs, trauma, or urinary obstruction.
Editorial use note: This page is written for owner decision support and preparation for veterinary care. It does not replace an exam, diagnosis, or treatment plan from the veterinarian who can evaluate the pet directly.

Emergency Symptoms - Seek Immediate Care
Call your vet or emergency clinic NOW if your dog shows: difficulty breathing, collapse or unconsciousness, severe bleeding, distended abdomen with retching (possible bloat), seizures lasting more than 3 minutes, suspected poisoning, trauma, or complete inability to urinate. For poisoning, also call ASPCA Poison Control: (888) 426-4435.
Vomiting
Vomiting is common but varies widely in severity. One episode after eating grass is different from repeated vomiting with blood.
When to Worry Less
- Single episode with no other symptoms
- Eating too fast or too much
- Mild dietary indiscretion (eating something unusual)
- Dog is otherwise acting normal and interested in food
When to Seek Care Promptly
- Vomiting multiple times in one day
- Blood in vomit (red or "coffee ground" appearance)
- Vomiting with diarrhea
- Unable to keep water down
- Lethargy or weakness with vomiting
- Possible foreign body ingestion
- Vomiting in puppies (they dehydrate quickly)
Emergency Signs
- Unproductive retching with distended abdomen (possible bloat/GDV)
- Vomiting with severe abdominal pain
- Suspected poisoning
Diarrhea
Loose stool has many causes, from dietary changes to serious infections.
When to Monitor at Home
- Soft stool but dog is otherwise normal
- Recent dietary change or new treats
- Single episode with no other symptoms
When to Seek Care
- Bloody or black, tarry stool
- Watery diarrhea, especially in puppies
- Diarrhea lasting more than 24-48 hours
- Diarrhea with vomiting, lethargy, or fever
- Signs of dehydration (dry gums, skin tenting)
- Unvaccinated puppies with diarrhea (parvo risk)
Not Eating (Inappetence)
Dogs occasionally skip meals, but persistent refusal to eat warrants attention.
Less Concerning Scenarios
- Skipping one meal but otherwise acting normal
- Hot weather or stress-related appetite decrease
- Picky eating in otherwise healthy dog
Seek Care If
- Not eating for more than 24-48 hours
- Accompanied by vomiting, diarrhea, or lethargy
- Weight loss visible or palpable
- Changes in water consumption
- Puppies not eating (they need consistent nutrition)
Coughing
Different types of coughs indicate different problems.
Types of Coughs
- Dry, honking cough: Often kennel cough or tracheal collapse
- Wet, productive cough: May indicate pneumonia or fluid in lungs
- Gagging cough: Possible foreign body or post-nasal drip
- Coughing at night or when resting: Possible heart disease
When to Seek Care
- Cough persisting more than a few days
- Difficulty breathing with cough
- Blue or pale gums
- Coughing blood
- Exercise intolerance with cough
- Fever, lethargy, or loss of appetite
Difficulty Breathing
Breathing problems are always urgent. Know the difference between normal panting and distress.
Breathing Emergency Signs
- Extended neck, elbows out, struggling for air
- Blue or purple gums or tongue
- Very rapid breathing at rest (more than 40 breaths/minute)
- Open-mouth breathing in situations that don't warrant it
- Collapse associated with breathing difficulty
- Sudden severe respiratory distress
These are emergencies requiring immediate veterinary care.
Musculoskeletal Symptoms
Rigid protocol adherence loses to attentive observation of your pet's small daily signals almost every time.
Limping / Lameness
Limping ranges from minor sprains to serious injuries or diseases.
Assessing Severity
- Mild: Slight favoring, still bearing weight
- Moderate: Clearly limping but will bear some weight
- Severe: Not bearing weight on the limb
When to Seek Care
- Non-weight-bearing lameness
- Visible swelling, bruising, or deformity
- Limping that doesn't improve with rest in 24-48 hours
- Limping accompanied by fever or illness
- Inability to get up or walk
- Dragging limb or loss of sensation
Back Pain / Spinal Issues
Back problems can range from muscle strain to serious disc disease (IVDD).
IVDD Warning Signs
Intervertebral disc disease (common in Dachshunds, Corgis, Basset Hounds, and other long-backed breeds) can cause paralysis if not treated promptly. Seek immediate care for: reluctance to move, hunched posture, yelping when touched, wobbly gait, dragging back legs, or loss of bladder/bowel control.
Urinary Symptoms
Outcomes are consistently better for owners who treat the individual animal's baseline as their reference, not the breed's average.
Changes in Urination
Urinary symptoms can indicate infections, diabetes, kidney disease, or urinary blockage.
Symptoms to Watch
- Increased urination: May indicate diabetes, kidney disease, Cushing's
- Straining to urinate: Possible infection, stones, or blockage
- Blood in urine: Infection, stones, or other urinary tract problems
- Accidents in house-trained dogs: Medical or behavioral causes
- Inability to urinate: EMERGENCY - possible blockage
Urinary Blockage Emergency
A dog that is straining but unable to produce urine may have an urinary blockage. This is a life-threatening emergency, especially in male dogs. Seek immediate veterinary care.
Skin and Coat Symptoms
Adapt to your dog sitting in your home and you will almost always outperform a by-the-book approach.
Itching and Scratching
Excessive scratching indicates an underlying problem that needs addressing.
Common Causes
- Allergies (environmental, food, contact)
- Fleas or other parasites
- Skin infections (bacterial, fungal, yeast)
- Dry skin
- Hot spots
When to Seek Care
- Scratching causing hair loss or skin damage
- Red, inflamed, or infected-looking skin
- Hot spots (painful, oozing areas)
- Scratching affecting sleep or quality of life
- Ear infections accompanying skin issues
Lumps and Bumps
Many lumps are benign, but new growths should always be evaluated.
Track These Details
- Size (measure it)
- How quickly it appeared or is growing
- Texture (firm, soft, attached to underlying tissue)
- Location
- Whether it bothers your dog
Your vet may recommend fine needle aspiration or biopsy to determine what a lump is. Many are harmless lipomas (fatty tumors), but early detection of cancerous masses improves outcomes.
Neurological Symptoms
Seizures
Seizures are frightening but often manageable with treatment.
During a Seizure
- Keep your dog away from stairs, furniture, and other hazards
- Do NOT put your hand near their mouth
- Time the seizure
- Speak calmly and soothingly
- Gently comfort them as they recover
Seek Emergency Care If
- Seizure lasts longer than 3-5 minutes
- Multiple seizures in a short period (cluster seizures)
- First-ever seizure (requires evaluation)
- Seizure in a puppy or senior dog
- Dog doesn't fully recover within an hour
Disorientation or Confusion
Sudden disorientation may indicate stroke, vestibular disease, or cognitive decline.
Vestibular Disease Signs
- Sudden head tilt
- Loss of balance, falling to one side
- Rapid eye movement (nystagmus)
- Nausea and vomiting
While vestibular disease often improves on its own, sudden onset should be evaluated to rule out stroke or other serious causes.
Eye Symptoms
Fit the plan to the animal you live with; the breed average is only a starting sketch.
Red or Irritated Eyes
Eye problems can progress quickly and may threaten vision.
Concerning Eye Symptoms
- Squinting or keeping eye closed
- Excessive tearing or discharge
- Cloudiness or change in eye appearance
- Visible third eyelid
- Rubbing at eyes
- Bulging eye (emergency)
Eye problems often worsen quickly. When in doubt, seek same-day veterinary evaluation.
