When to worry: symptoms that mean call the vet

Most of the time, a slightly-off day resolves on its own. But some signs mean don't wait. Here's how to tell the difference.

Call now / go to the ER

• Difficulty breathing, choking, or nonstop distressed panting at rest
• A hard, swollen, or bloated belly, especially with unproductive retching (possible bloat — fast and fatal in big, deep-chested dogs)
• Collapse, fainting, or sudden weakness
• Repeated vomiting or diarrhea, especially with blood
• Pale, white, or blue gums
• Seizures, or sudden disorientation
• Suspected poisoning
• Straining to urinate with little or nothing coming out
• A serious injury, heavy bleeding, or being hit by a car — even if they seem fine (internal injuries hide)
• Signs of severe pain — crying, trembling, hunching, or snapping when touched

Call today (same day)

• Vomiting or diarrhea lasting more than ~24 hours, or any in a young puppy or senior
• Not eating for more than a day
• Limping that doesn't improve, or a new swelling
• A squinting, painful, or injured eye
• Drinking or peeing a lot more than usual

The rule that never fails

When in doubt, call. A good clinic would always rather answer a worried question than miss a sick dog. You won't be "that annoying client" — you'll be a prepared owner.
