Surgical vs chemical desexing in male dogs

There are many benefits to desexing your dog, including preventing unwanted pregnancies, reducing aggressive behaviours and eliminating the risk of testicular cancer. In fact, studies have shown that a castrated dog lives about 14% longer than a dog who hasn’t been desexed. However, some pet owners – particularly of male dogs – are reluctant to have their animal desexed, for a range of reasons.

But did you know there is a temporary chemical alternative to surgical desexing for male dogs?

What is chemical desexing?

Chemical desexing or castration of male dogs involves the injection of an implant called Suprelorin under the skin.  The key ingredient in the implant is a hormone that temporarily suppresses the production of testosterone. There are two implants available – one lasts for 6 months and the other for a year. Once this time elapses, your dog’s testosterone levels will return to normal.

What does surgical desexing involve?

Surgical castration of a dog involves the removal of their testicles from the scrotum under general anaesthesia. Surgical desexing is a permanent procedure, meaning that once the testicles are removed, the dog will no longer be able to reproduce.

What are the pros and cons of chemical desexing?

Pros

If you’re unsure if you want to desex your dog, but would like to reduce or prevent aggressive behaviour, then chemical castration is a good option to see if surgical desexing will be effective.

Chemical desexing may be a good alternative If you’re considering showing or breeding your dog, as the results are temporary, and can be reversed at any time. Chemical castration is also a safer option for dogs who are older or have certain underlying health conditions which can make surgery under general anaesthesia riskier.

Cons

The main downside of chemical desexing is the cost. Being a temporary measure, you will need to have the implants replaced every 6-12 months, depending on the implant you choose. Chemical castration is very safe, with the main side effect being swelling at the injection site.

How do I decide what is right for my dog?

It’s important that you consult with your vet before making your decision on the method of desexing your dog. They can advise you on the best approach depending on your dog’s age, health, behaviour and any specific circumstances, and discuss in detail the pros and cons of surgical and chemical desexing.

Practical Tips

Understand the Benefits and Timing of Chemical Desexing

Chemical desexing involves injecting a Suprelorin implant under the skin that temporarily suppresses testosterone production for 6-12 months, offering a reversible alternative to surgical castration. This option is particularly valuable if you’re unsure about permanent desexing, considering showing or breeding your dog, or if your dog is older or has health conditions that make general anaesthesia riskier.

Weigh Cost Considerations Against Temporary Benefits

Consider that chemical desexing requires implant replacement every 6-12 months, making it more expensive long-term than surgical desexing, though it offers the flexibility to reverse the effects at any time. The main side effect is typically mild swelling at the injection site, making it a very safe procedure with minimal immediate risks compared to surgical alternatives.

Consult Your Veterinarian for Personalised Recommendations

Discuss with your vet the best desexing approach based on your dog’s age, health, behaviour, and specific circumstances, as they can provide detailed information about both surgical and chemical desexing pros and cons. Your veterinarian can help you determine whether the temporary nature of chemical desexing aligns with your long-term plans for your dog, including considerations for breeding, showing, or permanent behavioural management.
