Check Lidocaine for your dog
Enter your dog's details for a straight answer sized to them.
Why Lidocaine is dangerous
Lidocaine can be absorbed after chewing or swallowing creams and patches. Excess exposure affects the brain and heart and can also cause methemoglobinemia.
Signs to watch for
Drooling, vomiting, weakness, wobbliness, tremors, seizures, abnormal heart rhythm, pale or blue-gray gums
What to do next
Keep the bottle or packaging, count what may be missing, and call for case-specific guidance even if your dog looks normal.
Chewed patches can retain substantial drug even after use. Any swallowed patch, concentrated liquid, or significant cream exposure needs urgent advice.
Can I treat this at home?
Do not induce vomiting or give food, charcoal, or another medicine unless a veterinarian or poison specialist directs you.
When should I call the vet?
Call your veterinarian or an animal poison control center now with the product strength, amount missing, time, and your dog's weight.
