Heat in Bitches

Most Bitches start around 6-7 months of age.  They usually become attractive to dogs from the first day of heat but tend not to show interest in dogs until 7-10 days have passed.  Conception may occur if a bitch is mated at any time during her heat but is most likely around 10-12 days signs are first noticed.  Signs will usually disappear within 21 days.  The majority of bitches will continue to come "on heat" approximately every 5-9 months throughout their lives.

The need for heat control in Bitches
There are many reasons for heat control in bitches but the most important are:

• To prevent unwanted pregnancy

• Health advantages - to reduce the risk of uterine problems, mammary tumours and false pregnancy,

• Convenience - to avoid problems of messy bleeding, vulval swelling, attractiveness to dogs and the need to confine the bitch.

• Consistency - during her heat of other stages of the cycle

Remember, in most bitches, heat lasts for three weeks and occurs twice a year.

Method of heat control
There are two methods of heat control available:

• Surgery - operation known as "spaying", to remove the bitch's ovaries and uterus.  The bitch will not then come into heat but also she will not be able to have puppies.

• Hormonal control - bitches can be given an artificial hormone to prevent them coming into heat or shorten a heat that has just begun.

How is the hormone given?
Tablet preparations are available but can usually only be given for short periods of time.
An injection specially delveloped for the control of heat in bitches is usually started after the bitch has had her first season naturally.

Please see a veterinary surgeon for further advice on heat control to decide upon the best course of action for your bitch.
