What to Do if Your Dog Collapses or Passes Out

Collapse is a clear sign of an underlying health issue. But what could cause a dog to collapse? What should you do if your dog passes out? Read on to find out.

Dog Collapse & Fainting

Collapse is a sudden loss of strength that causes your dog to fall to the ground, with or without loss of consciousness. Dogs who collapse but remain conscious may express confusion or anxiety.

Fainting, passing out or syncope is a collapse with loss of consciousness, which may be accompanied by defecation or urination. Fainting can follow other symptoms such as staggering, disorientation, diarrhea, or general weakness and is considered to be a veterinary emergency.

Depending on the cause of the dog's collapse they may recover very quickly, jumping up and appearing perfectly normal. In other cases, they may stay in a lying position until assisted.

What To Do If Your Dog Collapsed

If your dog has passed out but recovers quickly contact your vet to let them know what has happened. Your veterinarian can let you know whether an examination is called for.

What to Do if a Dog is Unconscious

Remain calm and evaluate the situation.

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

Examine your dog for any clinical signs that may help your vet determine a cause for your dog's collapse.

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

During regular hours call your vet right away, 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.
