Can dogs eat paracetamol / acetaminophen (tylenol)?
Never give a dog paracetamol. It is not a safe human painkiller to share, and it damages red blood cells and the liver. If your dog is in pain, ask a vet for a drug licensed for dogs.

Do not wait for symptoms and do not try to make your dog sick unless a vet has told you to — some substances cause more damage coming back up. Have your dog's weight, what was eaten, roughly how much, and when, ready before you call.
What to do
Go to a vet immediately. There is an effective antidote, acetylcysteine, and it works far better the earlier it is given.
Signs to watch for
- brown or muddy gums
- swollen face or paws
- laboured breathing
- vomiting
- lethargy
- jaundice
- dark urine
When: 4–12 hours.
What makes it harmful
Acetaminophen and its reactive metabolite NAPQI
Dogs have limited capacity to conjugate acetaminophen safely. The surplus is converted to NAPQI, which depletes glutathione and then attacks liver cells directly. It also oxidises haemoglobin to methaemoglobin, which cannot carry oxygen — hence the characteristic muddy-brown gums.
