If your dog cannot have spinach or is simply not loving it, worry not. There is a variety of vegetables dogs can eat and get the same benefits. Each food has a unique nutrition composition therefore no vegetable can truly mimic that of spinach. However, there are vegetables that have a similar nutrition profile. Some of these vegetables include: Lettuce. Lettuce is a suitable replacement for spinach. It is however lower in nutrients but highly hydrating due to its high water content. Lettuce should ideally be given with other vegetables with higher nutritional value Kale. Kale has a very similar nutrition profile to spinach. Unfortunately, this similarity also means kale too has significant amounts of oxalic acid. Kale has lower amounts though and can be used in place of spinach. Collard greens. Collard greens are rich in vitamins and minerals making them excellent replacements for spinach. Their oxalate content is also not as concerning as that of spinach.  Arugula. Another healthy dark leafy vegetable that has a nutrition profile very similar to that of spinach without the downsides.   Green beans. These are very nutritious and packed with vitamin C, vitamin K, and manganese. They are also special because they contain more protein than most vegetables.   Cabbage. It has a slightly different nutrient profile as it is not a dark leafy vegetable but it is still loaded with lots of nutrients like antioxidants, vitamin C, and fiber.
