Generation Pup study on neutering

Dog owners reported whether they intended to neuter their dogs and their attitudes towards neutering.

People were less likely to plan to neuter their dogs if their dogs were just 16 weeks (four months) or younger; if they were owners of male dogs; if their dogs were registered with The Kennel Club; if they were intended as working dogs; or if the owners reported that they were experienced dog owners. 

Researchers found that dogs were less likely to be reported as neutered by 15 months of age if they were a pure breed; bred by their owner; living with other dogs and if their owner planned to breed from them at the point of acquisition (aged 16 weeks or less). 

Findings of the study

The most common reasons owners chose to neuter their dogs by 15 months of age were to prevent puppies and to reduce the risk of future health problems. 

The study also found that by 15 months of age, 90% of female non-neutered dogs had had their first oestrus. This is an important finding which adds evidence of when dogs may reach sexual maturity, as the timing of the first oestrus is often taken into account, combined with other factors such as dog size, when deciding when to neuter a dog. 

Exploring an owner's intention to neuter their dog can help veterinary professionals understand the reasons considered important by owners when deciding whether to opt in for this procedure.

In addition, the study found that purebred dogs in multi-dog households who were bred by their owner were less likely to have been neutered by 15 months.

During discussions with an owner, the dog’s home environment and history will need to be considered to allow personalised conversations when discussing neutering with a vet or vet nurse. 
 

Rachel Casey, our Director of Canine Behaviour and Research said:

“The study found that many owners neutered their dog to reduce the risk of future health problems.

Much is still unknown about the impact neutering can have on dog behaviour and a number of health conditions which develop later in life. This highlights the important role vets can play in educating owners about the health risks and benefits of both neutering and keeping their dog entire.

Bespoke conversations with veterinarians could increase owner understanding and allow them to make a more informed decision about their dog’s needs.”
