My dog with pre-existing liver disease ate a muffin that contained one ground clove. Is this especially risky for him?

Short answer

Yes, this carries added risk because cloves contain eugenol, a compound that can stress the liver. A dog with compromised liver function is less able to process this substance safely. The amount in one muffin is probably small, but it's impossible to know how his system will handle it. Watch for any worsening of his usual condition, loss of appetite, vomiting, or unusual lethargy over the next day. Given his health status, it's wise to call your vet, describe what he ate and his medical history, and follow their specific guidance.

Cloves — Food safety facts

Contain eugenol, which is irritating and can affect the liver in quantity.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Cloves is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.
