We recommend male dogs are castrated at 9 months of age.
Bitches are spayed before their first season, ie at 6 months, unless of a specific breed (eg Old English Sheepdogs, Dobermans, Red Setters)
Every animal is an individual and at times a vet may recommend a different timeframe for your pet.
We recommend male cats are castrated and females spayed between 4-6 months.
We recommend that both does and bucks are neutered at 4-6 months.
