Your vet places a resorbable implant between the dog’s shoulder blades, just as they would do for an electronic chip.
After the implant has been placed, an active ingredient is released at a constant rate, preventing the production of the hormones necessary for the formation of testosterone and other sex hormones for over six months. After a few weeks, hormone levels drop to a baseline, just like after a surgical castration, resulting in decreased sexual behaviours. You must wait several weeks after the implant has been placed for the dog to be sterile.
On the day of surgery, the dog needs to be fasted as the castration is done under general anaesthesia. The procedure consists in removing both testicles. For this, an opening must be made, a little behind the penis. It is then closed with stitches. Healing requires a dozen days on average. The dog’s reproductive capacity is then permanently removed.
