Dog Eating Oak Galls and Acorns: Toxicity Risks

A dog owner asked about risks of their pet eating oak leaf galls and acorns.

What Are Galls?

Abnormal plant growths induced by insect chemicals. Composed of plant tissue, sometimes housing mites.

Risk Assessment

• Galls: No documented toxicity to dogs. Any mites would die in stomach acid.
• Acorns/oak leaves: Listed on some "toxic to dogs" lists but generally low risk in moderation. Concerns: intestinal blockage (whole acorns), stomach upset from tannic acid (large quantities). Risk depends on dog size/age.

Recommendation

Discourage the habit but don't panic over occasional ingestion. Monitor for vomiting, lethargy, or blockage signs.
