Are Pinecones Toxic to Dogs?

Pinecones themselves aren’t necessarily toxic to pups, but vets wouldn’t say they don’t pose any risks.

“Pinecones aren’t poisonous to dogs in the way that chocolate or grapes are, but I wouldn’t call them harmless,” Dr. Ross says. “The sap and oils in pine can upset a dog’s stomach, and the cone itself is a physical hazard. In the ER, we worry far less about toxicity than about what a pinecone can do mechanically once it’s chewed up and swallowed.”

The Real Hazards of Dogs Chewing Pinecones

When it comes to the dangers of pinecones and dogs, the real risk is in the fact that pinecones are sharp and stiff, which can lead to a number of injuries.

“The scales are stiff and splintery, so they can scrape or puncture the gums, tongue and roof of the mouth, or get wedged between teeth,” Dr. Ross explains. “Swallowed fragments don’t digest well. They can irritate the stomach and intestines, and in some dogs, particularly small dogs or those that gulp large pieces, they can cause a blockage that requires surgery.”

Additionally, pinecones may end up carrying other harmful substances. “There’s also what’s on the pinecone to consider,” Dr. Ross says. “Cones on the ground may carry mold, lawn chemicals or pesticides, and decorative pinecones are often treated with scented oils, paint or glitter that can cause problems of their own.”

If your dog gets hold of a pinecone, look out for some signs and symptoms of potential trouble, such as throwing up or fatigue. “If your dog has eaten pinecone and you notice repeated vomiting, loss of appetite, lethargy, a painful belly or straining to pass stool, have them seen right away,” Dr. Ross says. “Those signs can point to an obstruction, and it’s much easier to treat when caught early.”

“Dogs that go after pinecones usually want something with texture to work on, so give them a safer outlet,” Dr. Ross recommends. “Sturdy rubber chew toys are a good choice, especially ones you can stuff with food and freeze. Dental chews accepted by the Veterinary Oral Health Council are another option. Match the size to your dog so the toy can’t be swallowed whole.”
