    5. Gila Monsters

    Gila monsters are rare, but eventful – they latch onto and chew on their victim for a long time, injecting venom from their teeth in the back of their mouth. “It can be very difficult to remove the Gila monster from its victim,” Dr. Tegzes says, “and dogs will often present to the veterinarian with the lizard still attached and biting!” The painful bite can cause neurological signs, but usually is not life-threatening.

    Location: Southwest.

    What to do if your pet is bitten: Don’t pull off the lizard with force. Often its teeth will detach and remain embedded in the dog. Instead, spray some water or rubbing alcohol onto the Gila monster’s nose, Dr. Tegzes says, and it will let go on its own.
