While nuts offer health benefits to dogs, many are toxic and can pose choking and obstruction hazards. Most nuts are high in fat, which can lead to obesity and pancreatic issues in dogs. Feeding your dog salted nuts can also lead to water retention and other complications, and some nuts, like almonds, are potential choking hazards. Here is a list of nuts that are toxic for dogs and should be avoided:

• Macadamia nuts: Very toxic to dogs. Can cause weakness, inability to walk, vomiting, tremors, and hyperthermia in dogs. Symptoms usually begin within 12 hours of ingestion.
• Almonds: Potential choking hazards and prone to mold like pecans and walnuts.
• Hazelnuts: Toxic to dogs.
• Pistachios: Toxic to dogs.
• Pecans: Potential choking hazards and prone to mold like almonds and walnuts.
• Walnuts: Potential choking hazards and prone to mold like almonds and pecans.

Peanuts, which are technically in the legume family, are safe for dogs in very small quantities, as long as they are unsalted and unseasoned. Cashews are also reportedly safe in small quantities, but both cashews and peanuts are too high in fat to make regular treats and could potentially be choking hazards. It is not a good idea to feed your dog nuts on a regular basis, and if your dog eats a large container of nuts, it could lead to pancreatic issues. It is always best to consult with your veterinarian before introducing any new food to your dogs diet.
