This is great information for pet parents who are adopting an in intact puppy. I would love the rescue organizations and shelters to study this research. I wish I had this information when I had to decide at what age and what procedure to use to spay my two dogs. The new methods of spaying and neutering are much healthier for our pets and well worth checking out when altering your pets. I, like most people, was strongly urged by many veterinarians to have my dogs spayed before six months so they wouldn't go into a heat.
Since then I have read many studies on spaying or neutering pets and the information is eye opening. Of course there are other ways to get hormone support if your pet has been altered. I am not promoting Dr. Becker's product but I want you to know that there are options for pets that have already been altered. The information in the video about altering our pets and losing the benefits of their natural hormones is excellent.
The research information from Dr. Karen Becker is in the YouTube video below.
