If you are not planning on breeding from your pet, neutering at a relatively young age can be beneficial both behaviourally and for physical health later in life.
Castration for male dogs
Speying for female (bitch)
We generally recommend:
Castration from 6 months of age.
Speying approximately 3 months after her first season. However, we can spey females before their first season.
Your vet will be happy to explain in more detail and make recommendations for your individual pet.
