Spaying of the female dog is done in order to avoid pregnancy by crossing of unknown, country or non-descript dogs. The spaying reduces the aggressiveness of the dog and can reduce the commonly encountered reproductive diseases such as pyometra.
This process also helps to control over-population of stray animals and in some countries experienced veterinarians remove the ovaries from the female dogs for the same. After the surgery care should be given more importance because if appropriate control measures are not taken then infections may start in the animal and end up in the development of peritonitis and eventually toxemia begins, which causes unwanted health problem. Eventually this may lead to death of the animal.
A female dog which has been spayed before the happenings of first heat will have no chance of developing mammary cancer, which is common in the dogs that have not been spayed. Normally a female dog comes to heat once in every eight months or so. During the heat process, bleeding starts in the vagina and dog may cross with unwanted male; however this activity is prevented by spaying. Adult dogs may often show signs of raised thirst, loss of hunger, puking etc. which are associated with pyometra.
Pyometra is basically having pus in the uterus. Pyometra not only agitates the animal, but also requires a lot of money for therapy. Pyometra can be completely avoided by spaying because in the case of spaying, you are removing both ovaries and the uterus.
Spaying your pet can be very good for the health of your pet and protect it from dangerous dog diseases. If you do not intend to breed your animal it is highly recommended that you spay it.
