I've been giving my 15 kg dog a few pine nuts as a daily training treat for weeks. Could this regular, small amount cause problems over time?

Short answer

Yes, daily feeding can cause problems. Pine nuts are very high in fat, and even a few each day adds up, potentially leading to pancreatitis or weight gain over months. In dogs, they've also been linked to a temporary metallic taste disturbance that might make your dog picky with his regular food. Stop using them as treats immediately. Switch to lower-fat options like small pieces of his kibble or commercial training treats. If you notice him turning away from his meals or any vomiting, mention the pine nut history to your vet.

High in fat; in dogs they have been linked to a temporary taste disturbance and liver upset.

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

Pine nuts 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

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

Pine nuts can turn up now and then, but not as a daily habit: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
