How long does a female dog need to recover after being spayed?

A female dog typically takes 10 to 14 days to recover from being spayed, with the first few days being the most critical for rest and minimal activity (no running, jumping) to allow the incision to heal and prevent complications like infection or stitching breakdown. Full internal healing can take longer, up to six weeks, but most dogs are cleared for normal play and walks by their vet around the two-week mark, often when sutures are removed.
