Hurricanes create pet hazards that last long after the wind stops.

After a storm, dogs may encounter:

  • Floodwater
  • Downed power lines
  • Broken glass
  • Nails
  • Splintered wood
  • Contaminated standing water
  • Displaced wildlife
  • Fire ants
  • Mold
  • Sewage

For pet owners:

Do not let dogs roam through storm debris or drink from floodwater.

Floodwater Is Not Safe Water

Floodwater may contain:

  • Sewage
  • Fuel
  • Pesticides
  • Household chemicals
  • Bacteria
  • Sharp debris

Do not let dogs:

  • Drink it
  • Swim in it
  • Walk through it unless unavoidable

Rinse After Contact

If a dog must cross questionable water:

  • Rinse paws
  • Rinse lower legs
  • Dry thoroughly

Prevent licking until cleaned.

Downed Power Lines

Treat every downed line as energized.

Keep pets far away from:

Do not approach to investigate.

Broken Glass and Nails

Storm debris may hide:

  • Nails

Use a short leash.

Do not let dogs run freely through cleanup areas.

Check Paws After Every Walk

Inspect for:

  • Cuts
  • Punctures
  • Embedded debris
  • Burns
  • Swelling

Small puncture wounds can become infected.

Mold and Wet Buildings

Flooded homes can develop mold quickly.

Keep pets out of:

  • Wet drywall
  • Moldy rooms
  • Contaminated carpet

until areas are safely cleaned.

Chemicals and Fuel

Storm cleanup may expose:

  • Gasoline
  • Oil
  • Antifreeze
  • Cleaning chemicals
  • Pesticides

Do not let dogs lick:

  • Puddles
  • Containers
  • Garage floors

Fire Ants After Flooding

Flooded fire ants can form floating rafts.

Keep pets away from:

  • Other snakes

Use a flashlight during:

Do not let dogs chase injured or exhausted wildlife.

Dead Animals

Keep pets away from:

  • Parasites

Mosquitoes After Storms

Standing water can increase mosquito activity.

Keep heartworm prevention current.

Drinking Water

If local authorities issue a boil-water notice, use safe drinking water for pets too.

Do not assume tap water is safe for the dog when it is not safe for people.

Food Safety

Discard pet food that has been:

  • Soaked
  • Contaminated
  • Stored in damaged packaging

Temporary Housing

At shelters, hotels or rentals:

  • Collar ID
  • Microchip
  • Contact information

Emergency Veterinary Care

After a major storm, some veterinary clinics may be:

  • Closed
  • Damaged
  • Operating limited hours

Best Post-Hurricane Pet Checklist

  • Short leash
  • No floodwater drinking
  • Avoid debris piles
  • Check paws
  • Rinse after exposure
  • Avoid downed wires
  • Watch for snakes/alligators
  • Keep heartworm prevention current
  • Use safe drinking water

The storm may be over.

The pet hazards are not.

For several days after a hurricane, assume every puddle and debris pile may contain something you do not want your dog touching.
