Dogs can have ham in small quantities, but it is generally not recommended as a regular treat or meal for them. Ham is not toxic to dogs, but it has high fat, sodium, and sometimes sugar content, which can lead to health problems like stomach upset, pancreatitis, dehydration, obesity, and even serious sodium poisoning if consumed in large amounts. Additionally, processed ham often contains preservatives like nitrates and nitrites that are harmful to dogs. Ham bones can also pose a serious risk of injury or internal damage. In summary, while a small piece of plain ham occasionally is unlikely to harm a healthy dog, feeding ham regularly or in large amounts is not safe or healthy for dogs. It is best to avoid giving dogs ham and opt for healthier, dog- specific treats instead.
