Reluctant to castrate your dog?

Why castrate your dog?

There are many reasons to consider castration:

  • Medical benefits, e.g. management of an enlarged prostate
  • Behavioural problems, e.g. excessive libido, urine marking, wandering
  • Prevention of unwanted reproduction

Previously surgical castration was the only option to achieve a long term solution.

Non-surgical option

Now there is a way to suppress testosterone without the need for surgical intervention.

A contraceptive implant is available that can be administered by your veterinarian. The resorbable implant is inserted under the skin between your dog's shoulders; there is no need for an anaesthetic or surgery.

It is implanted in a simple process similar to microchipping. The implant softens quickly, causing no discomfort. After implant placement, an active ingredient is released steadily preventing the production of the sex hormones and testosterone.

Mode of action

non-surgical castration in dogsTestosterone is generally reduced 2-3 weeks following implantation. It takes around 6 weeks for the dog to become infertile due to sperm which is stored in the reproductive tract.

Infertility lasts for a minimum of 6 months or a minimum of 12 months and trials of up to 4 consecutive implants have shown fertility returns after treatment ends.

Benefits of non-surgical castration

  • Diseases dependant on testosterone (e.g. prostatic enlargement) may be alleviated without the need for surgery.
  • Aid in the control of behaviour problems – if you need to address your dog’s behavioural problems which may be testosterone related you can ‘road test’ castration to see if this has a positive effect on your dog’s behaviour.
  • Reversible reproductive control.

Important: Behaviour problems are not always due to testosterone. Please talk to your vet who will be able to advise if this product is best for your dog.
