Are two Brazil nuts worse for a 15 kg dog than a handful of almonds in terms of toxicity?

Short answer

Yes, Brazil nuts pose a higher specific risk. While almonds can cause stomach upset or pose a choking hazard, Brazil nuts are extremely high in selenium and fat. Just two nuts could potentially lead to selenium toxicity in a medium-sized dog, causing symptoms like vomiting, diarrhoea, and in severe cases, neurological issues. Almonds are not recommended either, but their primary risk is gastrointestinal blockage or pancreatitis from fat. It's best to avoid giving any nuts to your dog and contact your vet if they've eaten Brazil nuts, especially if signs like lethargy or tremors appear.

Extremely high in fat and selenium — a few nuts can cause selenium toxicity. Avoid.

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

Brazil 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.
