In male dogs, both testes are removed; this is known as ‘castration’. In female dogs, either the uterus is removed or both the uterus and the ovaries; this is known as ‘spaying’.

Spaying a female dog eliminates the ability to reproduce, and your dog will no longer come into season. Females can be neutered from six months of age; for most breeds, we suggest spaying females before they have had a season, known as pre-season. If your dog is older than six months or has already started having seasons, we would need to wait three months after a season to ensure we are operating at the best possible time.

At what age are dogs neutered and spayed?

Neutering is usually carried out at around six months of age for males and pre-season for female dogs, reducing the likelihood of females developing mammary cancer. We would also consider your dog’s breed, size, overall behaviour and other risk factors to provide the most suitable recommendation for your dog based on the latest evidence.

Male dogs older than six months can be neutered at any stage; however, we would still consider the dog’s breed, size, overall behaviour and other risk factors upon discussion of the procedure.

If your dog is not spayed before her first season, we would wait three months after the season.

Should I let my dog have one litter before spaying her?

This happens to be a common question, and there are no known health benefits to letting your dog have a litter; this is also the same for cats and rabbits.

General anaesthesia

Your pet requires a general anaesthetic for neutering; here at St Clair Veterinary Group, we have measures in place to ensure their safety during the procedure. A dedicated Registered Veterinary Nurse (RVN) will monitor your pet throughout their surgery and recovery. All anaesthesia comes with some form of risk; however, these are very low, especially neutering, as pets are often young, fit, and healthy when having this procedure.

Risk levels of anaesthesia increase with a pet’s age, certain breeds and if your pet has any underlying health conditions. We can perform a pre-anaesthetic blood test before your pet’s surgery, to detect any underlying illnesses; this can be discussed when booking in for the procedure and on the day of their surgery. Your pet will receive a premedication to relax them and will also receive two types of pain relief. Rest assured the St Clair Veterinary Group team will be with your pet every step of the way.

Your pet will stay the day with us

On the day of the procedure, please bring your dog on a secure harness or lead; during the admission appointment, we will discuss the procedure and go through the consent form. Please note we must gain a signature from the registered owner (over 18) or authorised agent on the consent form. Your dog, cat or rabbit will be admitted as a ‘day patient’, and they will be discharged later that day once our team are happy with how your pet has recovered.

Find your local St Clair Vets

During your pet’s discharge appointment, the team will go through everything you need to know about caring for your pet after their surgery and their pain relief medication. We are always at the end of the telephone for you and your pet, so please contact us if you have any further questions once you have your pet settled back at home.
