What happens if a dog eats spinach?

Generally, a dog eating a moderate amount of spinach will not have negative effects and can even add some nutrition. Spinach is a healthy vegetable rich in vitamins A, C, and K and minerals such as iron, calcium, and magnesium. It also contains natural antioxidants that help keep the dog’s immune system healthy.

However, note that eating large amounts of spinach may cause digestive issues like diarrhea, vomiting, and bloating. In addition, spinach contains oxalic acid, which may affect calcium absorption and lead to abnormal bone development.

Therefore, when feeding spinach to a dog, control the amount and keep it within about 10% of its normal diet.
