The question of toxicity regarding Maclura pomifera fruit, commonly called hedge apples or Osage oranges, and their effect on canines is frequently raised. While the fruit is not definitively classified as poisonous in the traditional sense, it contains compounds that can cause gastrointestinal upset in dogs if ingested.
The primary concern stems from the fruit’s size and texture. Dogs may attempt to chew or swallow pieces of the hedge apple, leading to potential choking hazards or intestinal blockages. Furthermore, the sap within the fruit can be irritating to a dog’s digestive system, potentially resulting in vomiting or diarrhea. Historically, there have been anecdotal reports of adverse reactions, though scientific evidence supporting widespread systemic toxicity is lacking.
