Pufferfish Poisoning and Dogs in Florida

Pufferfish can be extremely dangerous if eaten.

The major toxin associated with many pufferfish is tetrodotoxin, a potent neurotoxin.

For dog owners:

Never let a dog eat a pufferfish, whether fresh, dead or washed onto the beach.

Why Pufferfish Are Dangerous

Tetrodotoxin can interfere with nerve and muscle function.

Severe poisoning can lead to:

• Weakness
• Loss of coordination
• Paralysis
• Breathing failure

Dead Fish Are Still Dangerous

A pufferfish does not have to be alive to be hazardous.

Do not let dogs:

• Bite
• Chew
• Carry
• Eat

a pufferfish carcass.

Beach Walks

Pufferfish may wash ashore with other fish.

Use extra caution around:

• Wrack lines
• Fish kills
• Red tide events
• Fishing areas

Keep the dog on a short leash.

Fishing Trips

If you catch a pufferfish:

• Keep dog away
• Do not leave fish on deck
• Do not let dog lick slime or tissue
• Dispose of it according to current fishing rules

Signs of Possible Poisoning

Seek emergency veterinary help if a dog that may have eaten pufferfish develops:

• Drooling
• Vomiting
• Weakness
• Tremors
• Difficulty walking
• Difficulty breathing
• Collapse

Do Not Wait for Symptoms

If you know or strongly suspect the dog ate a pufferfish:

Contact an emergency veterinarian immediately.

Do Not Induce Vomiting Without Guidance

Because severe poisoning can affect muscle control and breathing, home treatment can be risky.

Follow veterinary instructions.

Bring Evidence

If safe, take:

• Photo of fish
• Remaining carcass in sealed container
• Time of exposure

Do not handle unknown fish with bare hands if avoidable.

Pufferfish and Human Food

Florida also has strict public-health warnings regarding consumption of certain pufferfish.

That is another reason never to treat pufferfish as casual pet food.

Best Prevention

• Short leash on beach
• No scavenging
• Keep fish carcasses away
• Closed fish box
• Immediate cleanup after fishing
