5. Excessive Vomiting or Diarrhea
If your dog vomits multiple times or has explosive diarrhea, especially with:
- Lethargy
- Drooling
- Dehydration
- Blood in stool
Then it may be something serious like gastroenteritis, pancreatitis, or toxic ingestion. Small dogs are especially at risk of rapid dehydration.
6. Distended or Painful Abdomen
A swollen or hard belly is a red alert. Your dog might be suffering from:
- Bloat (Gastric Dilatation-Volvulus or GDV)
- Internal bleeding
- Tumors
- Organ failure
Bloat, in particular, can kill a dog within hours. Signs include:
- Unsuccessful vomiting
- Panting
- Swollen belly
- Restlessness
7. Seizures or Tremors
If your dog suddenly has a seizure, collapses, or has violent shaking, take them to the vet immediately. Possible reasons include:
- Epilepsy
- Brain tumor
- Toxic food (like xylitol or chocolate)
- Low blood sugar
Even a single seizure can be dangerous if it lasts too long or recurs quickly.
8. Sudden Blindness or Disorientation
A dog that suddenly bumps into things, looks confused, or stares into space may be experiencing:
- Stroke
- Brain injury
- Severe infection
- Eye injury or glaucoma
Sudden vision loss or behavior change is never normal. Your vet can help identify the cause with eye and neurological exams.
9. Trouble Peeing or Pooping
If your dog tries to pee or poop but nothing comes out, or it whines when doing so, this could mean:
- Urinary tract infection
- Kidney stones
- Bladder blockage
- Constipation or rectal issues
In male dogs, a urinary blockage can become life-threatening within hours.
10. Persistent Coughing or Gagging
A chronic cough, wheeze, or gagging sound could mean:
- Kennel cough
- Tracheal collapse
- Heart disease
- Lung infection
It’s especially serious if it interferes with breathing, sleeping, or is paired with lethargy. Senior dogs and small breeds are more at risk.
Bonus Signs That Shouldn’t Be Ignored
- Pale or blue gums: Indicates lack of oxygen or shock.
- Dragging legs or paralysis: May be spine-related or neurological.
- Unexplained weight loss: Can be caused by cancer, diabetes, or organ disease.
- Unusual lumps or growths: Could be benign—but also cancerous.
What You Should Do in Emergencies
- Call your vet immediately
- Use an emergency 24/7 animal clinic if your vet isn’t available
- Don’t self-medicate your dog
- Keep a list of toxic foods and emergency contacts handy
