Neutering your pet – Dog Castration: A Guide for Pet Owners


Dog castration, also known as neutering, is a common surgical procedure performed on male dogs. This guide aims to provide comprehensive information to help you make an informed decision about this important aspect of pet care. By understanding the procedure, its benefits, and post-operative care, you can ensure your dog leads a healthier and happier life.

What is Castration?

Castration involves the surgical removal of a dog’s testicles. This results in a significant decrease in testosterone levels, which can help reduce certain undesirable behaviours. Additionally, it prevents your dog from fathering unwanted litters. It’s important to note that dogs can remain fertile for up to six weeks post-operation, so precautions should be taken during this period.

Why Castrate Your Dog?

Castration offers numerous benefits:

·         Reduces undesirable behaviours such as urine marking, straying after female dogs, and aggression.

·         Prevents testicular cancer, a common ailment in older male dogs.

·         Reduces the risk of certain prostate diseases.

·         Lowers the likelihood of some anal tumours and certain hernias.

Common Concerns

Weight Gain: Post-castration, dogs may be prone to weight gain if overfed. It’s crucial to adjust your dog’s diet and ensure regular exercise to maintain a healthy weight.

Personality Changes: Significant personality changes are uncommon. However, castration can help improve undesirable behaviours linked to testosterone. If you’re concerned, discuss with your vet about temporary hormone implants to gauge the effects before making a final decision.

When should you castrate your dog?

Castration can typically be performed from six months of age. Early castration is often recommended for dogs exhibiting unwanted behaviours or if an entire female dog lives in the same household. Dogs with undescended testicles should be castrated by six months to prevent cancer risks.

What does the castration procedure entail?

·         Pre-Operative Consultation: We will discuss the procedure and assess your dog’s fitness for general anaesthesia.

·         Fasting: No food should be given from the evening before the operation day, but water is allowed.

Day of Operation:

Your dog will receive pain relief and mild sedation. Under general anaesthesia, a small incision is made in front of the scrotum, and the testicles are removed. Your dog will have to spend a night at the clinic for observation and post operative care. Rest and restricted activity are crucial for 10-14 days. An “Elizabethan cone” is needed to prevent wound licking and infection.

Post-Operative Care

Follow-up checks 3 days after discharge from the clinic will ensure the wound is healing properly and to advise when normal activities can resume.
