Recognizing Poisoning Symptoms in Dogs

Dogs can be exposed to various toxins, leading to different poisoning symptoms. Common signs include vomiting, diarrhea, seizures, blood in stool, lethargy, loss of appetite, bruising, nosebleeds, difficulty urinating, and irregular heartbeat.

Watch for these specific indicators of poisoning:

  • Excessive Drooling
    A sign of nausea, which may involve foaming at the mouth.
  • Appetite Loss
    Changes in eating habits often signal health issues.
Signs of poisoning in dogs
If your dog skips meals frequently and exhibits other poisoning symptoms, seek immediate veterinary care.
  • Coordination Problems
    Indicate potential brain toxin effects, making the dog appear unsteady or dizzy; xylitol in peanut butter can cause such issues.
  • Poisoning signs can vary based on substance type:

    • Neurological Symptoms
      Caused by toxins like strychnine, tobacco, aspirin, antidepressants, alcohol, marijuana, flea repellents, drain cleaners, and dishwasher detergents. Plants like horse chestnuts and buckeyes may also cause neurological effects.
    • Heart-related Signs
      Irregular heartbeat may stem from oleander, milkweed, jimson weed, or mountain laurel ingestion.
    • Anemia Indicators
      Bruising, nosebleeds, and blood in stool are symptoms, often resulting from rat poisons, garlic, onions, sweet clover, or bracken fern.
    • Gastrointestinal Issues
      Loss of appetite, vomiting, or diarrhea can result from consuming garbage, toxic plants (like holly, English ivy), chocolates, snake bites, or other harmful substances.
    • Kidney Damage
      Symptoms include urination difficulties, caused by plants like caladium, pigweed, Easter lily, or philodendron.
    • Liver Damage
      Caused by medications such as acetaminophen and plants like tansy or rattlesnake root.
    To identify poisoning, veterinarians may induce vomiting; if vomit appears blue, it indicates poisoning. Analyzing vomit helps determine toxins consumed, with samples sent to laboratories for confirmation.
