There is a lot of information and misinformation out there about the best time to neuter your pet dog. Vets and vet nurses are required by their governing body to continuously update their medical knowledge and be aware of current research in veterinary medicine. Previously, we recommended early neutering to prevent certain types of cancer and behaviour problems. However, modern research has shown that the link to early neutering and the prevention of mammary tumours is not substantiated. It has also been shown that neutering early does not prevent aggressive behaviour, in fact, in may increase aggression, especially in female dogs. Early neutering can also lead to increased incidence of joint problems and some cancers. (Frontiers in VetSci, 7 Jul 20).

Therefore, we are now recommending that all female dogs be spayed AFTER their first season. For large breeds, we may suggest that the you wait until the bitch is 18 -23 months. This allows the bitch to mature through puberty and become more settled in behaviour and also for her joints to develop fully. For male dogs, the timing of neutering depends primarily on the breed type and size of your dog: the larger the dog, the later neutering should take place. Currently, we are suggesting that all dogs that will be greater than 20kgs (44 lbs/3 stone) as adults, be neutered at the age of 12months or later. Giant breeds should not be neutered before 18-23 months. Nervous dogs should not be neutered until they have developed confidence, as lowering testosterone levels will only make the dog more anxious and may lead to fear aggression.  Once the dog has matured emotionally, as well as physically, neutering can take place.

Basically, every dog is an individual and we need to discuss with you when is the best time for both you and your dog to have your dog neutered.
