TL;DR: Chemical burns are life-threatening emergencies that require immediate veterinary care and a photo for rapid triage. These injuries continue to damage tissue until treated and can lead to internal organ damage if ingested or absorbed.
What is a chemical burn and what does it look like on my dog?
- A chemical burn occurs when skin contacts caustic substances like household cleaners, pool chemicals, or battery acid.
- Unlike heat burns, chemical burns continue to damage tissue as long as the substance remains on the body.
- Lesions may appear as red, raw skin, or in severe cases, as white or blackened patches of destroyed tissue.
How urgent is it if my dog has a chemical burn?
- Chemical burns are high-priority medical emergencies because substances can be absorbed into the bloodstream.
- Once absorbed, these chemicals can cause internal organ damage or systemic toxicity.
- Dogs often lick the affected area, which can lead to severe chemical burns in the mouth and esophagus.
- Contact an emergency veterinarian immediately if you suspect your dog has a chemical burn lesion.
Why should I provide a photo of the burn to the veterinarian?
- A high-quality photo allows the veterinarian to assess the depth of tissue damage and the extent of the spread.
- This visual information helps the vet provide specific first-aid instructions, such as whether to flush the area with water.
- Triage professionals can determine if certain neutralizing agents are necessary while you are in transit to the clinic.
Clinical Context (Merck Veterinary Manual)
In cases of chemical burns from corrosives (acids or alkalis), immediate care involves copious flushing of dermal or ocular exposures with water or physiologic saline, with eye flushing lasting a minimum of 20 minutes, followed by fluorescein staining to check for corneal injury. For dermal exposures, bathing with mild shampoo and thorough rinsing is recommended. Animals exposed to respiratory irritants should be moved to fresh air and monitored for dyspnea, with pulmonary edema treated as necessary. For significant oral and/or esophageal burns, a gastrostomy tube may be required for nutritional support during healing, while topical treatments for dermal or ocular burns should be implemented as needed, and analgesics may be indicated in severe cases.
