What to Do if Your Dog Collapses or Passes Out

Common Reasons for a Dog's Collapse

One of the most common reasons a dog might collapse is heatstroke. Heatstroke occurs when a dog’s body temperature rises to a dangerous level, often due to being in a hot environment without access to water or shade. Dogs with thick fur, short noses, or overweight are susceptible to heatstroke.

What To Do If Your Dog Collapses

If your dog loses consciousness but quickly recovers, contact your vet to inform them of the incident. Your veterinarian will advise you on whether an examination is necessary.

What to Do if a Dog is Unconscious

Remain calm and evaluate the situation.

Make sure that your pup is in a safe space away from danger. Use a calm voice to reassure your pet, and if necessary, use a blanket to move your dog.

Examine your dog for any clinical signs that may help your vet determine the cause of its collapse.

• Was your dog behaving normally before the collapse?
• Is your dog struggling to breathe?
• Are they bleeding?
• Is your dog's abdomen swollen? 

Call your vet immediately during regular hours, explain the situation, and arrange an emergency appointment. If your usual veterinary clinic is closed, contact your nearest animal emergency hospital or head straight over.

Note: An unconscious dog may wake up feeling confused or anxious. This can lead to uncharacteristic behavior, including aggression. Use extra caution when transporting your pup to the vet for care.

Preventive Measures for a Safer Environment

Preventing your dog from collapsing or passing out involves taking proactive steps to ensure their safety and health. Here are some preventive measures:

• Regular health check-ups can help detect underlying conditions that might cause your dog to collapse. Ensure your dog’s vaccinations are up to date and on a regular schedule for parasite prevention.
• Provide plenty of water and shade to keep your dog cool during hot weather and avoid excessive exercise. Never leave your dog in a parked car, even temporarily.
• Avoid strenuous exercise during hot weather and ensure your dog is well-hydrated. Be mindful of your dog's limits, especially if it is older or has pre-existing health conditions.
• Ensure your home and yard are free from hazards that could cause your dog to collapse, such as toxic plants, chemicals, or unsecured swimming pools.
