What is the medical or non-surgical castration option?
It is a resorbable contraceptive implant administered by your veterinarian. It is inserted under the skin between your dog’s shoulders; there is no need for an anaesthetic or surgery. It is suited to dog owners who want the benefits of castration without the need for surgery, anaesthetic, or testes removal.
How does it work?
It is implanted in a simple process similar to microchipping. After implant placement, an active ingredient is released steadily, preventing the production of the sex hormones and testosterone.
Testosterone is generally reduced 2–3 weeks following implantation. It takes around 6 weeks for the dog to become infertile due to sperm stored in the reproductive tract. Depending on the implant used, sperm production is prevented for at least 6 months or at least 12 months. Once the implant wears off the dog’s fertility will gradually return.* To maintain infertility, an implant can simply be administered either every 6 months or every 12 months depending on the implant used.
The implant is safe and not associated with significant side effects.
