Are the hypericum berries on the pumpkin plant poisonous to dogs?

Yes, hypericum berries, which come from the St. John's Wort plant, can be toxic to dogs if ingested in large amounts. They can cause gastrointestinal upset, lethargy, and even more severe reactions depending on the quantity consumed. While pumpkin itself is safe for dogs, it's important to keep them away from any hypericum berries to prevent potential toxicity. If you suspect your dog has ingested them, it's best to consult a veterinarian.
