Small Talk - Winter 2018

Although the reduced risk of some diseases, such as tumours of the reproductive tract and breast tissue, is well recognised in dogs after neutering, some studies indicate that certain other tumours and cruciate disease may be more likely after neutering in certain breeds. These factors can complicate the decision to neuter or not, but it has to be remembered that the evidence in these studies are often not substantial enough to be definitive. The level of risk reported also represents a very small statistical chance of a problem in any one individual animal - it must be remembered that ‘increased risk’ does not mean ‘this will happen to my dog’. Usually other health and behavioural advantages of neutering, such as those mentioned above, are deemed more important in any individual case. If neutering has been decided upon, another consideration is the age at which it should occur, with evidence that neutering dogs early could increase the risk of certain conditions in some larger breeds. Thus, unless other factors are overriding, a sensible recommendation would be to delay neutering, certainly in large breeds, until over a year of age, pushing this out to 18 months for giant breeds. Surgical neutering is normally performed on healthy, young animals and so risk is minimal, although one must understand that there is always a small risk with any anaesthetic or surgical procedure. Animal behaviour is coming to the fore as a topic that must be considered before neutering is performed. Neutering in an attempt to solve behavioural problems should only be done after professional advice. It could be detrimental in some cases. For example, hormones can help with confidence levels; fearful, unconfident dogs could worsen after neutering, thereby compounding their problems. A vet may wish to refer you to a colleague registered to advise on behavioural issues before neutering is contemplated. For other behaviours temporary neutering using medication may be considered for a test period. small talk 11 In summary... Current thought prevails that more often than not, particularly for bitches, the benefits of neutering out- weigh the risks but this may not be the case for every individual pet. The days of broad-brush canine neutering policies are drawing to a close. Speak to your vet about your pet. Factors relating to breed and behavioural disposition can all be assessed properly so that an informed decision can be made as to whether neutering is in the best interests of your dog and if so, when it is best done. Factors can complicate the decision to neuter or not, but it has to be remembered that the evidence in these studies are often not substantial enough to be definitive. ‘‘ ‘‘
