What to Know About Using Pepper Spray on Dogs

Before pepper spraying an aggressive canine, be sure you understand proper use to maximize results:

  1. Wind direction: Aim the spray slightly into the wind so the blowback doesn’t hit you when deployed.
  2. Distance: The effective range is typically 10 to 20 feet for dog pepper spray products. Don’t wait until the dog is right on you.
  3. Spray area: Aim for the dog’s eyes, nose, and face for best results. These mucous membranes feel the irritants quickly.
  4. Amount: A one-second burst is often sufficient. Too much spray can incapacitate the dog longer than desired.
  5. Type: Not all pepper sprays are equal. Look for a reputable brand explicitly designed for deterring dogs.
  6. Practice: Test firing your spray beforehand ensures you’ll be ready if needed in a real dog encounter.

Following these guidelines can help maximize the performance of pepper spray against an attacking dog. Take time to educate yourself on the proper use of this self-defense tool.

  • Use a gentle shampoo or dish soap to wash the face and coat. Avoid getting it in your dog’s eyes.
  • Call your veterinarian, who can provide specialized eye drops, oral medication, or ointments to relieve symptoms. Never give your dog any medicine without consulting your vet first.
  • Once home, place your dog in a quiet space with fresh air and access to water to recover. The effects typically resolve within a few hours.
  • Monitor for abnormal lasting effects like appetite changes, eye redness, or skin irritation, and update your vet. Severe reactions are rare but can occur.
