Cane Toad Poisoning: How to Protect Your Pet in Puerto Rico

Cane Toad Poisoning: How to Protect Your Pet in Puerto Rico

Cane toad poisoning is one of the most dangerous and frequent emergencies among dogs in Puerto Rico. At VETS PR in Caguas, our veterinarians treat numerous cases each year, especially on rainy or humid nights when these toads are most active. The cane toad produces a potent toxin that affects the heart and nervous system in a matter of minutes.

Dogs are most affected because they tend to chase or bite these toads without realizing the danger they pose. Recognizing the symptoms and acting quickly can save your pet's life.

Early Symptoms

The toxin is quickly absorbed through the gums. Early signs include excessive salivation, vomiting, red gums, rubbing the mouth, and visible signs of irritation.

Advanced Symptoms

If left untreated, the pet may suffer seizures, irregular heartbeat, tremors, difficulty walking, or collapse. These symptoms can appear very quickly.

What to Do Immediately

Rinse the dog's mouth with running water, always with its head down to prevent it from swallowing water. Do not rub the mouth. After rinsing, it is mandatory to seek immediate veterinary attention.

What Not to Do



Do not put your hands inside their mouth.

Prevention in Puerto Rico

Cane toads are common throughout the island, so prevention is key:

  1. Keep an eye on your dog outdoors at night.
  2. Do not leave food out.
  3. Maintain good outdoor lighting.
  4. Learn to identify these toads; they are larger than the native ones.
