Dogs can eat clementines in moderation. Clementines are not toxic to dogs and can provide some nutritional benefits like vitamin C, hydration, low calories, and fiber. However, there are risks such as their high sugar content, acidity which might upset some dogs' stomachs, and the fact that peels and seeds should be avoided as they can cause digestive irritation or choking hazards. It's best to peel and seed the fruit, cut it into small pieces, and offer it occasionally as a treat. Dogs with sensitive stomachs or specific health issues like pancreatitis or diabetes should avoid citrus fruits altogether. Monitoring the dog for any adverse reactions after eating clementines is also important.

In summary, dogs can safely eat peeled and seeded clementine segments as an occasional treat, but it should not be a regular part of their diet.
