Are Daddy Long Legs Venomous to Dogs?
The common name "daddy long legs" actually refers to two different types of arachnids: harvestmen and cellar spiders. While both are often mistaken for spiders, they are quite different in their biology and behavior.
Harvestmen (Opiliones)
- Not venomous: Harvestmen do not have venom glands or fangs. They are harmless to dogs.
- Defensive mechanism: Their primary defense mechanism is to secrete a foul-smelling liquid from glands on their legs, which can deter predators.
- Not poisonous: While the liquid is unpleasant, it is not considered poisonous to dogs.
Cellar Spiders (Pholcidae)
- Weak venom: Cellar spiders do have venom glands, but their fangs are very small and weak.
- Not harmful to dogs: Their venom is not strong enough to cause significant harm to dogs or other mammals.
- Not a threat: Even if a dog were to encounter a cellar spider, it is unlikely that the spider would be able to penetrate the dog's skin with its small fangs.
In short, neither harvestmen nor cellar spiders pose a significant threat to dogs. While cellar spiders have venom, it is not potent enough to harm dogs.
What to do if your dog encounters a daddy long legs
- Stay calm: Most likely, your dog will not be harmed by the encounter.
- Observe: Keep an eye on your dog for any signs of irritation or unusual behavior.
- Seek veterinary attention: If your dog shows any signs of distress, contact your veterinarian.
