This morning Dr Hannah had a lovely stroll along the Taroona foreshore and came across a puffer fish, which is toxic to dogs!
Puffer fish contain a toxin called tetrodotoxin which is one of the most deadly natural poisons. The toxin is found on the skin and internal organs of the puffer fish, and is approximately 1,200 times more poisonous than cyanide. A lethal dose of tetrodotoxin is smaller than the head of a pin, with one fish containing enough poison to kill 30 people.
Tetrodotoxin is extremely fast acting. Within minutes, signs of poisoning start to become apparent, and after a few short hours paralysis will set in. In severe cases, puffer fish poisoning proves fatal within an hour.
Early signs and symptoms include:
🐡 Vomiting
🐡 Excessive drooling
🐡 Panting
🐡 Dullness and lethargy
Symptoms will then progress to:
🐡 Trembling
🐡 Wobbly walking pattern
🐡 Blue-tinged coloured gums
🐡 Dilated pupils
🐡 Muscle tremors and seizures
Quickly signs and symptoms will become more severe to include:
🐡 Difficulty breathing
🐡 Unable to blink
🐡 Complete paralysis of the whole body
🐡 Coma
How is puffer fish poisoning treated?
If you see your dog eat or mouth (licking or chewing) a puffer fish take them to the vet immediately. On your arrival your vet will perform tests, such as blood tests, to determine the severity of the poisoning. As there is no antidote for tetrodotoxin poisoning, treatment involves:
🐡 Inducing vomiting to remove the toxin
🐡 Administering of activated charcoal to assist in the removal of the toxin
🐡 Soluble fat fluids may be used to dilute the toxin
IV fluids for hydration
🐡 Oxygen therapy if they are experiencing breathing difficulties
🐡 In cases of severe paralysis, mechanical ventilation (life support) may be needed
If treatment is sought many pets will recover within a day or two. Without treatment, pets who become paralysed are not likely to recover.
