Spaying dogs later lowers urinary incontinence risk, study finds
Urinary incontinence affects around one in 30 female dogs in the UK.
Researchers find 20 per cent drop in risk compared to those spayed earlier.

Delaying spaying female dogs until they are between seven and 18 months old causes a 20 per cent drop in the risk of early-onset urinary incontinence, a new study has found.

The research, conducted as part of the VetCompass Programme at the Royal Veterinary College (RVC), used anonymised clinical records from over 30,000 bitches under first-opinion veterinary care in the UK born between 2010-2012.

From these records, the researchers looked at a random sample of 1,500 bitches, 612 (40.8 per cent) of which had been spayed when they were between three and six months old and 888 (59.2 per cent) of which had had the operation between the ages of seven and 18 months.

They found that the dogs aged between seven and 18 months when spayed had 0.8 times the likelihood of developing early-onset urinary incontinence compared to bitches spayed between three and six months.

Because the two groups studied were balanced across other characteristics including breed, veterinary group, insurance status and chronic illness, the researchers believe a causal link can be inferred.

This method of veterinary causal inference from large databases, which is being developed at the RVC, allows researchers to try to answer questions for which a clinical trial might not be practical or ethical.

Around one in 30 female dogs in the UK are affected by urinary incontinence, and spayed bitches are over three times more likely to experience it.

Previous research by the RVC found that Dalmatians, Hungarian vizslas, Dobermans, Weimaraners, shar-peis and boxers are the breeds most at risk of early-onset urinary incontinence.

Camilla Pegram, a PhD student at the RVC and lead author of the paper, said: “This study is now one in a series using an exciting new approach, allowing us to determine ‘cause’ rather than being limited to ‘association’.

“Spaying is something that every owner and vet will need to consider at some stage and so the findings of this study can feed into spay decision-making.

“Although a decision to spay a bitch is based on many other factors other than urinary incontinence risk, the results suggest early-age spaying should be carefully considered and well justified.”

The study has been published in the journal Plos One.

Special imports digital service set to change

News Story 1
 From Monday, 15 July, Special Import Certificate (SIC) applications will only be accepted via the Veterinary Medicines Directorate's (VMD's) new special imports digital service.

The original online special import scheme will be decommissioned. The VMD says that the new service is easier to use, more secure and reliable, and meets accessibility legislation.

The VMD is urging veterinary surgeons who have not yet signed up for the new service to do so before 15 July. The new digital service can be accessed here

RCVS course explains concerns process

A free, online course from the RCVS Academy has been launched, designed to clarify RCVS' concerns procedure.

The content will give veterinary surgeons and veterinary nurses a better understanding of the process, and what they can expect if a concern is raised about them. It includes details of common concerns.

The interactive resource has been developed in collaboration with Clare Stringfellow, case manager in the RCVS Professional Conduct Team.

Ms Stringfellow said: "We appreciate that concerns can be very worrying, and we hope that, through this course, we can give vets and nurses a better understanding of the process and how to obtain additional support."

The course can be accessed via the RCVS Academy. Users are encouraged to record their learning for CPD.
