True fern plants are non-toxic to dogs.
True ferns are vascular plants that belong to the Polypodiopsida class. They do not have flowers or seeds, and reproduce through spores. They are used worldwide not only for landscaping gardens or livening up interiors. Some true fern species even have culinary and medicinal purposes.
Multiple reports state that true ferns are non-toxic to dogs. The American Society for the Prevention of Cruelty to Animals (ASPCA) lists some true fern species that are non-toxic to cats. Examples include the Boston fern, brake fern, and common staghorn fern. Other sources state maidenhair fern and bird’s nest fern as non-poisonous to both canine and feline pets.
On the other hand, there are other fern plant varieties that are harmful to dogs. Emerald fern, fern palm, and winter fern are some examples. Different toxic compounds such as alkaloids and saponins contained in the leaves and berries of the plant can easily poison your pet.
What to do if your dog accidentally comes into contact with, chews, or eats fern plants: It all depends on what type of fern plant your dog comes across during a walk outside or while playing with your plants. If he brushed against a true fern or tried a small nibble of its leaves, no adverse effects should occur.
But if you suspect that he came across a toxic fern plant, contact his veterinarian immediately. Keep an eye on your pet and observe him for symptoms of poisoning. Diarrhea, drooling, pale gums, nausea, vomiting, tremors, convulsions, agitation, unsteadiness on feet, abnormal heart rate, and difficulty in breathing are common signs. In addition, your dog may suffer from allergic dermatitis. This may manifest as dry skin, little bumps, hair loss, and redness in the affected area.
In summary: Due to the difficulty in identifying safe and unsafe fern plants, it’s essential to do sufficient research before growing a fern plant at home. When taking your dog out on a walk, keep him away from ferns that may be possibly toxic. In addition, keep your pooch protected by checking these lists from Pet Poison Helpline, ASPCA, and PetMD.
