  • Rinse the skin thoroughly with lukewarm water if there is dermal exposure.
  • Avoid giving any home remedies or antidotes without veterinary guidance.

At the veterinary clinic, treatment typically includes:

  • Decontamination: Activated charcoal administration to bind toxins.
  • Supportive care: Intravenous fluids to maintain hydration and electrolyte balance.
  • Medications: Anti-nausea drugs, anticonvulsants if seizures occur, and pain relief.
  • Monitoring: Close observation for changes in vital signs and neurological status.

Potential Outcomes and Prognosis

The prognosis for dogs exposed to boric acid depends on several factors including the amount ingested, promptness of treatment, and the general health of the dog. Mild exposures usually result in full recovery with appropriate care. However, severe poisoning can lead to complications such as kidney failure, coma, or even death if left untreated.

Preventive Measures to Protect Dogs from Boric Acid

To reduce the risk of accidental poisoning, pet owners should observe the following precautions:

  • Store boric acid-containing products securely out of reach of pets.
  • Avoid using boric acid-based insecticides or powders in areas where dogs frequent.
  • Use alternative, pet-safe pest control methods when possible.
  • Educate family members and visitors about the dangers of boric acid to pets.
  • Regularly inspect the environment for any spilled or accessible products.
