Can my dog eat Spinach?
Use caution
Safe in small amounts — high oxalates can stress kidneys.
What this means
Spinach contains oxalic acid, which blocks calcium absorption and can damage the kidneys over time with repeated large feedings. In small amounts it is fine and nutritious. Dogs with kidney disease should avoid it entirely.
Symptoms to watch for
Note for medium dogs (20–60 lbs)
A small leaf or two occasionally is unlikely to cause harm.
