How many slices of pepperoni can my 20 kg Labrador eat in one sitting before the salt and fat become a problem?

Short answer

A single slice of pepperoni is unlikely to cause harm to a 20 kg Labrador, but anything more than that starts to matter because of the high salt, fat, and spice content. The bigger concern is the pizza it usually accompanies, which may contain garlic or onion — both toxic to dogs. Keep pepperoni to an absolute minimum, no more than one small slice on rare occasions, and watch your dog for vomiting or diarrhea over the next 24 hours. If those signs appear, call your vet for guidance.

Salt, fat and spices. Tiny amounts at most, and watch for the pizza it comes on.

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

Pepperoni 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.

Why these cautions matter

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
