Deciding whether to spay
Spaying or neutering a female dog is not a small operation, so owners should think carefully about all the pros and cons before deciding.
The main advantages of spaying are preventing pregnancy, preventing infection of the uterus (pyometra), preventing ovarian or uterine cancer and reducing the likelihood of mammary (breast) cancer, all of which can be life-threatening. It also prevents the inconvenience of having a bitch in season with unwanted attention from male dogs.
The main disadvantages are major surgery with associated risks, an anaesthetic with associated risks and the increased likelihood of urinary incontinence in later life. Fortunately, the risks involved in anaesthesia and surgery are very small indeed compared with the risks of the other conditions which are prevented by spaying. Urinary incontinence in later life is a nuisance but not very common, and can usually be controlled by drugs.
There is no medical reason to let a bitch have one litter before spay, in fact some of the benefits like protection against mammary tumours, are lost if the operation is delayed. Unless an owner is committed to having a litter, with all the work and expense that can be involved, and the bitch is also suitable in temperament and free of any hereditary problems, then breeding should not be considered…………..
