Frogs can be poisonous to dogs, but it depends on the species. While many common backyard frogs are not seriously harmful, some toads and certain frogs secrete toxins that can be very dangerous or even fatal to dogs if licked or ingested. The most toxic are cane toads and Colorado River toads, which produce potent skin secretions that affect a dog's nervous system and heart. Symptoms of poisoning include drooling, foaming at the mouth, pawing at the face, vomiting, difficulty breathing, seizures, and disorientation. Immediate veterinary attention is critical if poisoning is suspected. Some non-poisonous frogs, like green tree frogs, can cause irritation, vomiting, and diarrhea but generally are not fatal. Dogs interacting with frogs should be monitored closely, and if they lick or bite a frog, their mouths should be flushed with water and a vet consulted promptly. In summary, certain frogs and especially toads can be toxic to dogs, so caution is advised to prevent dogs from coming into contact with them, particularly in areas where toxic species like cane toads are common.
