The Daily Puppy reports that dogs who are discharged after spaying surgery may vomit from the medications or be unsteady on their feet for two days. Some dogs try to scratch their wounds, and others are unable to return immediately to their regular diets. The Daily Puppy recommends keeping recently spayed dogs in clean, quiet areas while minimizing their activity level.
The Daily Puppy warns that dogs who were recently spayed should be discouraged from running, jumping, playing and excessive physical activity because movement may rip open their stitches. Pet owners should contact their veterinarians immediately if the dog has a fever, seems to be in intense pain, is exceptionally lethargic or shows signs of infection at the surgery site.
Besides the issues involved with recovery from surgery, dogs may experience lifelong behavioral changes after the operation. The ASPCA indicates that pet owners may see a decrease in breeding-related behavioral problems after spaying. Female dogs may become less aggressive. They may also become less irritable, lose the drive to roam and urinate less frequently. The ASPCA explains that the biggest behavior changes happen in dogs who are spayed before their first heat. Older female dogs who are accustomed to frequent urination, fighting or roaming while in heat may continue these behaviors after being spayed.
