Most experts agree that if dogs eat spinach, there is no immediate danger to their health, provided it is given in moderation and is thoroughly prepared and washed. However, before you ever give your canine companion any human food, it is best to understand all of the risks and potential health benefits!
Can Dogs Eat Spinach?
If your pup ever sneaks a leaf of spinach off your plate, you don’t need to worry about any health ramifications. Spinach is one of the healthiest vegetables for humans, and dogs can benefit from many of its nutrients and minerals. Packed with antioxidants, oxalates, dietary fiber, vitamins A, C, K and B, iron and protein, spinach can deliver a significant boost to your pup’s overall health, provided you give it to them properly. 
Spinach comes in many forms, but raw spinach is the best option for your dog, not least of all because it is the type it will probably like the most. However, there are some dangers to feeding raw spinach to your dog, such as any pesticides or residue that may be present on the leaves. Therefore, thoroughly wash any spinach before you give it to your dog. Furthermore, to prevent constipation or other digestive issues, be sure to only give your dog spinach in moderation. A few spinach leaves every other day should be enough, as there is no reason to overfeed a dog human food. They should be getting a balanced diet from their dog food; human food should be seen as an occasional treat or supplement.
Is Spinach Good For Dogs?
The impressive nutrient composition of spinach can be beneficial for your dog. It includes improving circulation, treating indigestion, stimulating the metabolism, and aiding bone strength, among others.
High levels of iron can help stimulate blood flow and promote healthy circulation in your pup. 
With a wide range of B vitamins, spinach is able to promote the metabolism in many ways. In your dog, these vitamins help with skin problems, nervous system issues, vision and immune system strength, among others. 
Reduces Stomach Issues
Spinach has a good amount of dietary fiber and soluble oxalates, which can help to promote healthy bowel movements and a smooth passage of food through the gut. This will also clear up symptoms of diarrhea or constipation. 
Improves Bone Density
As dogs age, they tend to grow weaker, and their joints become less flexible. To prevent a painful aging process for your pooch, eating mineral-rich supplemental food like spinach can really help. 
There is a small amount of protein in spinach, which dogs require for all of the same growth and development processes as humans, in addition to the protein required for repair in their body.
