My dog with pre-existing liver disease ate a slice of ham baked with a few whole cloves—should I be worried?

Short answer

Yes, you should be cautious and monitor closely. Cloves contain eugenol, a compound that can be irritating and may affect the liver, especially in a dog whose liver is already compromised. The amount from a few cloves used in cooking is likely small, but the combination with fatty ham adds another layer of digestive risk. Watch your dog for any new signs like vomiting, diarrhoea, loss of appetite, or increased lethargy over the next 24-48 hours. Given his condition, it's wise to inform your veterinarian about this incident so they can advise you based on his specific health history.

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.
