Knowing basic first aid for your dog can mean the difference between life and death. This guide covers the most common emergencies with clear, step-by-step instructions. First aid is a temporary measure — always contact your vet as the priority.

Poisoning

  • Common poisons: chocolate, grapes/raisins, xylitol (sweetener), slug pellets, antifreeze, ibuprofen, rat poison
  • DO NOT make your dog vomit unless specifically told to by a vet
  • Note what was eaten, how much, and when
  • Animal PoisonLine: 01202 509 000 (24/7, £35–45 per case) — they assess whether a vet visit is needed
  • Take packaging/photos to the vet

Bloat / GDV (Gastric Dilatation-Volvulus)

This is the most time-critical canine emergency. Fatal within hours without surgery.

  • Signs: Unproductive retching (trying to vomit, only white foam), swollen/hard belly, restlessness, drooling, collapse
  • Most common in large, deep-chested breeds (Great Danes, German Shepherds, Boxers, Setters)
  • Action: Call your emergency vet immediately. Drive straight there. Do NOT give food/water or massage the belly

Heatstroke

Rule: Cool first, transport second.

  • Signs: Excessive panting, bright red gums, drooling, vomiting, collapse, seizures
  • Move to shade/cool area immediately
  • Pour/spray cool (NOT ice-cold) water over body — focus on neck, belly, thighs. Use a fan if available
  • Do NOT use ice or ice-cold water — this constricts blood vessels and traps heat
  • Transport to vet once cooling has started

CPR (Cardiopulmonary Resuscitation)

For dogs that have stopped breathing and have no heartbeat:

  • A — Airway: Tilt head back gently, open mouth, clear any obstruction
  • B — Breathing: Close mouth, seal your lips over nostrils, give 2 rescue breaths (watch chest rise)
  • C — Circulation: 30 chest compressions at 100–120/min (rhythm of “Stayin’ Alive”), then 2 breaths. Repeat
  • Continue until you reach a vet or the dog regains consciousness

FAQs

When should I go to an emergency vet?

Go immediately if your dog has: difficulty breathing, collapse, suspected poisoning, bloat symptoms, continuous seizures, severe bleeding, inability to urinate, or major trauma. Don’t wait — call ahead so the vet team can prepare. Most practices have an out-of-hours number that redirects to an emergency service.
