Our Contract Allows for Spay/Neuter to be performed only after the age of 14 Months, and must be Performed by the age of 16 months. I have very strict guidelines with penalties for not Spaying/Neutering or (DeSexing) in the time allowed. Performing a Spay/Neuter before 12 months is a risk to the Dogs longterm Health. If your Veterinarian doesn't agree, then you find a different Veterinarian that will agree. Remember that I'm the one you have the Contract with, not your Veterinarian. Their is lots of YouTube videos out there with Veterinarians explaining why Spay/Neuter performed at a young age is harmful to the longterm health of the Dog. You can do your own research on this matter if you wish too, but in the end you are under a very strict Contract on this matter. Finding the right Veterinarian is key in pet ownership. Look for the Holistic Approach
