Steps to Take In A Pet Emergency

If you are experiencing a veterinary emergency, follow these steps.

  • Call Ahead If Possible - During regular business hours call us right away. After hours, call the emergency animal hospital listed above to let them know you are on the way.
  • Follow Instructions Provided - When you call to notify the emergency pet hospital that you are on your way, you may be given instructions on how to administer first aid or make your pet as comfortable as possible. Follow those steps as carefully as you can.
  • Remain Calm - Remain calm and be careful around your pet. When an animal is in pain they often react negatively toward anyone trying to help and could bite or scratch.
  • Bring Your Pet In For Care - Do not put yourself at risk! Safely bring your pet to our Port Jefferson veterinary clinic or the after-hours emergency vet locations above.
