Acids, which are chemicals with a pH < 7, can result in severe tissue injury to pets. Common sources of acids include household products like: battery fluid, toilet bowl cleaners, vinegar, metal cleaners, anti-rust compounds, hair wave neutralizers, and drain cleaners. Pets may be exposed dermally (through the skin) or after accidental ingestion (orally). Typically, acids are bitter to taste, and result in immediate pain on contact. Severe injury to the eyes, skin, gastrointestinal tract, and respiratory system can be seen. Treatment includes immediate decontamination (by flushing the exposed area), anti-ulcer medication, fluid therapy, and symptomatic supportive care. Severe poisoning can result in rupture or perforation of the intestines, or severe tissue injury. Immediate veterinary attention is recommended.
