Did you know?
Spinach originated in ancient Persia (modern Iran) and spread along trade routes to China and then to the Arab world. It reached Europe via Spain around 1000 CE. The Popeye cartoon from the 1930s boosted spinach consumption in the US by 33% among children — though Popeye's spinach strength was based on a German scientist's decimal error that overestimated iron content by a factor of 10.

What You Need to Know
Spinach is nutritious but contains oxalic acid which binds calcium and can cause kidney stress with regular large feeding. Occasional small amounts as a food topper are fine for healthy dogs. Dogs with kidney disease or kidney stones should avoid spinach entirely. Baby spinach has slightly lower oxalic acid than mature spinach.
Breed-Specific Notes
Avoid in breeds prone to kidney stones.
