Neutering your male dog​

​Castration is the removal of testicles from male patients. From a health point of view, it can have many benefits for your dog. 

​It eliminates the risk of testicular tumours, and reduces the threat of prostatic disease and of hernias developing later in life. 

​It will also help with undesirable behaviours such as tendences to escape, roam and fight other dogs, as well as sexual behaviours including indoor urine marking and discharges. However, it will not calm your dog down or change any other non-related behaviour issues. 

​You should consult with your vet on when to have your dog castrated, but generally we recommend that small dogs have the operation between six and 12 months, medium dogs at 12 months, and larger dogs between 12 and 18 months. 

​Neutering your female dog

​Spaying is the removal of the ovaries and/or uterus from female patients, and also has a range of health and behavioural benefits. 

​It eliminates the risk or pregnancy and phantom pregnancy, serious womb infections called pyometra, and ovarian and uterine cancers. Breast cancer instances can also be reduced, or even eliminated.

​It also means that your dog will not come into season, also known as heat, in which it will attract the attention of male dogs and may see changes in behaviour. 

​You may choose to have your dog spayed before their first season, in order to avoid the issues above. However spaying before the first season is not the best option for all bitches. Timing of the procedure is very important and something we take very seriously here at Caerphilly. We provide a free discussion with the vet at 6 months of age where your little lady's breed, weight, temperament and growth will all be assessed. 

​Neutering your male cat

​We recommend castrating cats at four months, at which stage they will be capable of breeding – even with siblings and parents. 

​As with dogs, neutering cats has a range of health and behavioural benefits. 

It reduces your cat’s desire to roam and to fight with other cats. This in turn means they are less likely to go missing, be hit by cars and have less chance of contracting feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) which are transmitted by cat bites and reproductive activity.

​It will also reduce aggressive behaviour associated with testosterone in your cat, as well as stopping your cat from spraying urine to mark territory, and making urine smell less strong.

​Neutering your female cat

​As with male cats, females can breed from four months, and should be spayed before this. 

​Female cats can eliminate similar health concerns to female dogs through spaying, including cancer of the womb or ovaries and pyometra, a potentially life-threatening womb infection.

​It also means that your cat will not come into season, which can cause behavioural changes and stress for your cat. If a female cat is in heat, unneutered male cats will be attracted to your property, with associated problems such as urine spraying and fighting. 

​Neutering rabbits

​It is important for rabbits’ happiness that they live in pairs or groups, otherwise they can become lonely. 

​However, if they are not neutered, they can develop aggressive, territorial behaviour connected to their hormones. Furthermore, if male and female rabbits live together they will produce litters. 

​Spaying female rabbits also stops them from developing cancer of the uterus – up to 80% of un-neutered females develop cancer of this kind. 

​Female rabbits should be neutered at around 16 weeks, as long as they are healthy and weigh at least 1kg, while male rabbits should be castrated at around 12 weeks, once their testicles have descended.
