Dogs are curious by nature, and that curiosity sometimes leads them to chew or eat things that can make them seriously ill. Knowing the signs of poisoning can help you act quickly if the worst happens.
Common Sources of Poisoning
Household chemicals, human medications, certain foods like grapes and chocolate, rodent poison, antifreeze, and toxic plants are among the most common culprits. Even small amounts of some substances can be dangerous.
Signs to Watch For
Vomiting, diarrhea, drooling, lethargy, loss of appetite, tremors, seizures, difficulty breathing, and unusual behavior can all indicate poisoning. Symptoms can appear quickly or be delayed by hours, depending on the toxin.
What to Do If You Suspect Poisoning
Try to identify what your dog was exposed to and how much, and gather any packaging or plant material if possible. Call your veterinarian or an animal poison control hotline right away, don't wait for symptoms to worsen, and don't attempt to induce vomiting unless instructed to do so by a professional.
Prevention Tips
Store medications, cleaning supplies, and chemicals well out of reach, keep human food and trash secured, and research any new plants before bringing them into your home or yard.
