Urgency level: High priority

Contact your regular veterinary hospital

What to do next

Contact your regular veterinary hospital ASAP and monitor your dog closely

  • If your regular veterinary hospital is open, contact them now. If they are closed, it is probably safe to wait until morning.
  • Monitor your dog closely for any new symptoms or changes in behavior. If the dog collapses again or becomes very lethargic or non responsive, contact an emergency veterinary hospital right away.
  • Be careful handling your dog after they collapse. Especially in seizures, a dog may be confused and bite. Give them a moment to come out of the episode.


Why it’s high priority

Collapse requires veterinary attention even if your dog has recovered

  • Any condition that causes collapse requires veterinary attention ASAP. Since your dog is acting normally right now, it is not an emergency but you should contact your regular veterinary practice.
  • Our main concerns in this case are heart disease, respiratory disease, and seizures, though there are many potential causes of collapse. If collapse is caused by a chronic disease, it will likely get worse and your dog may suffer a more severe episode in the future.


Home care tips

Keep your dog quiet and restrict exercise

  • Keep your dog quiet and calm. Depending on the underlying condition, sometimes collapse can be triggered by exercise or stimulants in the environment.
  • Restrict exercise (only short leashed potty breaks) until you have seen a veterinarian.
  • Depending on your dog’s condition, you may want to transport your dog in their crate/kennel or on something rigid, such as a pet or utility wagon. A possible cause of collapse is spinal injury, so take care to not aggravate the injury.
