You feed your dog raw defrosted spinach she is now sick could be kidney problem you have caused this?
While spinach is not considered toxic to dogs in small amounts, some dogs may experience GI upset after eating it. However, there is no evidence to suggest that feeding a dog raw, defrosted spinach would cause kidney problems. Kidney problems in dogs are more commonly caused by underlying medical conditions, such as infections, autoimmune diseases, or congenital defects. If you are concerned about your dog's health, it is always best to take them to a veterinarian for an evaluation.
