Cashews are nontoxic, making them safe for dogs to consume. However, feeding your furry friend cashews should be done in moderation.

Like most nuts, cashews have a high fat content, and too much consumption will lead dogs to develop a slew of health issues such as pancreatitis and obesity.

When sharing these nuts with your dog, make sure that they are not mixed with other nuts as some varieties are toxic to him.

If they contain flavoring, salt, and spices, avoid tossing even a few pieces at him. These nuts could potentially cause damage to his digestive tract, which can result in diarrhea, vomiting, and stomach pain.

Sodium toxicity, hypertension and renal problems may also occur due to their high salt content.

Chestnuts are generally safe for dogs to eat, but there are some things to keep in mind. To avoid potential health issues, it’s best to serve chestnuts plain without any added seasoning or flavoring. Additionally, raw chestnuts should be avoided due to their high levels of tannins.

While chestnuts are high in fat, they can be given to your dog in small amounts as an occasional treat. However, it’s important to remove the shells first to prevent choking and crush the nuts into smaller bits before sharing them with your pooch.

To avoid potential health issues, it’s best to limit the amount of peanuts your dog eats and offer them sparingly in small amounts.

Be careful what forms of peanuts you share with your dog too. Raw or roasted ones are safe as long as they are free from salt, flavoring, and spices. Always monitor your dog as he eats peanuts to prevent him from choking.
