Female dogs should be spayed at 6 months of age. Spaying before the first heat greatly reduces the incidence of mammary tumours later in life and also rules out the possibility of an accidental first litter.
Males dogs can be neutered from 4 months of age. Neutered males are less likely to wander and urine mark if neutered young but we recommend large breed dogs are left entire till about 12 months of age to allow further development as they take longer to mature.
We strongly recommend the desexing of all dogs that are not intended for breeding.
