Canine Chemical Neutering

talalogoa

Chemical neutering is a medical treatment that reduces sex hormone activity.  The hormone treatments available vary from country to country.  In the UK, both injectable and tablet forms are available. Males recieve an injection of Tardak, an anti-testosterone injection, which will  not protect against testicular cancers later in life, while bitches are given Delvosterone to suppress seasons.  This does not protect a bitch from mammary tumours and it can increase the likelyhood of a womb infection (pyometra) developing. Pyometra reduces fertility and often requires emergency surgery. Other possible side effects include swelling of the mammary glands and increase in mammmary cancer.  Hormonal conditions such as diabetes and false pregnancy may also arise.Tardak is most effective in suppressing male testosterone linked to behaviour such as aggression and hypersexuality.

Chemical neutering (hormone treatments) can provide a temporary fix without the need for surgery.  In dogs destined for breeding it has a useful advantage as once stopped the bitch will subsequently come into heat. Treatment may either be given to supress a heat when the bitch starts to show signs or be given at regular intervals between seasons to postpone the heat completely, but it is never a long-term option and is generally advised that no more than two heat cycles are suppressed in a row.  Only bitches that are fully mature and which have had their first season should be treated.  When treatments are stopped, the bitch usually comes into heat between two and nine months later.

It can be effective and safe but surgical neutering removes more of the active hormones and is more effective.  Also medicines are only effective in the short term and they do have potential side effects such as increased appetite, excessive thirst and increased urination.  The possibility of side effects depends on the type of treatment used so owners need to think carefully before starting treatment.

The cost of chemical neutering is variable.  It is generally cheaper in the short-term than surgery but should only be regarded as a temporary fix to surgery.

A Tardak injection will last for approximately a month, while Delvosterone can last for several months.
