When making the imperative decision of the timing of spaying and neutering, I want to make available research-based information to you all before you speak to your veterinarian. When you discuss your circumstances it is of the utmost importance to be informed when it is in your pet’s best interest, especially since your dogs are prone to breed-related orthopedic problems and certain health problems. Research is showing the timing and the sex are critical factors in spaying and neutering. Below are the two major important papers you should read and discuss with your health provider. Both studies appeared about the same time in 2013.
I’m posting them for all to read since we make the best informed decisions for ourselves and our pets. Each one of you has unique circumstances, and should make decisions that are best for you and your puppy's life. Old and young animals are especially vulnerable with the risk and complications of surgery and anesthesia, this is a decision to be made between your family and veterinarian.
