For a dog to be neutered, two essential steps should be carried out without fail:
1) A Complete Blood Test: Even if your dog has had a healthy and uneventful life, a complete blood test is an absolute must before the spaying surgery. This ensures that all the necessary parameters are within range and your dog is fit for anaesthesia. A complete blood test, including CBC, Liver Function Test (LFT), Kidney Function Test (KFT), is essential unless it has been done in the last 7 days and the values have been within range. Complications in the blood values, particularly haemoglobin (Hb), platelet count (PLT), liver (ALT/SGPT) and kidney values (BUN, Creatinine) are of concern and might warrant a delay in the procedure, if seen.
Besides these, there are other parameters to be considered, based on which your veterinarian may decide to proceed with the surgery or not. In certain cases, additional tests like an ultrasound, chest X-rays, or an ECG may be carried out to assess appropriate functioning in dogs with risks.
2) Fasting: Fasting is extremely important before a dog neuter surgery to prevent your dog from inhaling food or vomit during anaesthesia, minimising the risk of complications. The exact duration for fasting is debated and varies based on the surgeon’s preference. However, the usual window is 6-8 hours off food and 4 hours off water before the surgery. Don’t worry, your dog will be provided with the essential nutrients through an IV before and during the surgery. In case your dog ingests food or water during the fasting window, inform your veterinarian right away. You do not have to feel guilty or ashamed- accidents happen. Remember, dog neuter surgeries are mostly elective and can be delayed; your dog’s safety should always be a priority.
