Pine toxicity in your dog

Norfolk island pine trees appear naturally in temperate forests and are cultivated throughout the United States. They are grown for landscaping purposes and are commonly sold as Christmas trees.

The poison is not considered fatal, although vomiting, diarrhea, and lethargy may follow ingestion, so it's definitely an unpleasant experience for both you and your dog.

Your dog may be poisoned by chemicals

The wood used to build outdoor structures, furniture, and other objects may be treated with chemicals to repel the elements. Pieces of treated lumber can contain toxic arsenic compounds, which are poisonous to both dogs and humans. Chewing the wood is certainly dangerous, but your dog can even become ill by eating food or drinking water from the surface. Common signs of arsenic poisoning in dogs include:


  • Lack of stability while standing or walking
  • Excessive salivation or drooling
  • Severe digestive distress
  • Sensitivity to touch or pain in a dog's mouth or gastrointestinal tract, prompting aggressive reactions
  • Loss of consciousness

It's important to regularly seal decks that have been treated with toxic chemicals to prevent arsenic from leaching out. Do not burn, saw, or power wash the material around the home because the dangerous chemicals could remain in your dog's environment. And it's not just indoors. Common garden fertilizers and pesticides are toxic to dogs, causing an upset stomach if your dog ingests small quantities and more serious dog health problems if ingested in larger quantities.

  • Bleeding from the mouth, including the gums or tongue
  • Labored breathing accompanied by gagging or coughing
  • Blood in your dog's stool
  • Whimpering, agitation, or other signs of pain with no discernible cause

Are pine cones bad for dogs?

People and some animals can develop compulsions to nibble on nonfood objects. This condition is called pica. "Pica does occur in dogs but a nutritional deficiency is not a cause for pica in dogs," says Dr. Jordan Kautz, a veterinarian at Crestview Veterinary Clinic in Austin, Texas. "Horses can have nutritional pica and cats can have anemia, causing pica, but dogs will not."

While chewing on random objects is a normal phase of development for puppies and dogs, the habit can become ingrained to the point of dysfunction. It can also stem from infections, hormonal imbalance, and parasites as well as stress and neurological disorders. If your dog displays an insatiable compulsion to consume wooden objects or any other nonfood object, it's important to get them to the veterinarian for a checkup.
