What should I do if my pet ate a household chemical?
Call your vet immediately. Different chemicals require different responses, and the wrong action can make things worse. Bring the product label with you to the vet so they can determine the best course of treatment.
How do I pet-proof my home?
Lock all chemicals in child-proof cabinets. Keep trash cans lidded. Pick up dropped medications immediately. Do not leave detergent pods within reach. Keep garage doors closed. Store antifreeze and rat poison in locked cabinets. See our complete pet proofing guide for a room-by-room checklist.
