Spaying your female dog is usually an easy decision, but is a major surgery which will have a recovery time in which your dog needs some special care. Even though a spay surgery may leave your dog sick for a few days, rest assured it is one of the very best things you can do for her health in the long run.
If possible, pick your dog up from the vet the same day as her operation. Unless your dog had special health circumstances surrounding her spay, insist on taking her home the same day. Unless your vet is staffed 24hrs (this is very unusual unless it is an emergency clinic) hospitalized pets are caged and alone all night- dogs carefully transported home can be checked on throughout the night and can begin to recover at home where they feel safe and comfortable and will produce less stress hormone. Follow your vet's advice regarding post-op female dog after spay surgery need to rest pain medication. Remember that dog's bodies are very different from our own. Even though a spay is major abdominal surgery, their bodies heal very quickly. If your dog begins to feel too good, she will be more active and will be more likely to open her incision. Pain tells a dog whether she should rest or play, run around the house or stay in bed. If your dog is being too active, decrease the pain medication a bit so her brain will get the signal that pain sends telling her to rest.
Once you get your dog home from the vet you should keep her very comfortable for the first 24-48 hours. A familiar bed with a blanket and a hot water bottle is great to keep her at ease and warm. She probably won't appreciate being touched much but quietly remaining near her may be comforting for her. If you have young children in your home, put your recently spayed dog in a quieter area where she won't be bothered. (Remember, dogs in pain are the MOST likely to bite!) Follow your veterinarian's instructions regarding feeding, but remember not to feed too much. You may want to feed soft food or let kibble soak for a few minutes to help your dog get enough water. Within a day or two she will be up and around again, and in three to four days you'll be struggling to restrict her activity.
Your vet will probably advise low activity for 10-14 days, but as long as you restrict jumping, rough play, and all-out running for that time your dog should be fine. You should check her incision every day for signs of inflammation or infection. The scar from a spay incision is typically gone within several months, but can be sped up with a supplement or topical application of Vitamin E.
