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.

Webinar to explore history of KC breed registers

News Story 1
 A free webinar exploring the development of the Kennel Club's registration system and the evolution of closed breed registers has been announced.

Hosted by Dr Alison Skipper, veterinary and research advisor at the Kennel Club, the webinar will delve into the development of the registry and how the changing landscape of scientific knowledge has shaped breeding practices. It will also look at what this means for the future of pedigree dogs.

The session will culminate with a look at The Kennel Club's ongoing and future engagement in this area, with a chance for attendees to put forward their thoughts and questions for discussion.

This event takes place on Microsoft Teams on Tuesday, 10 June at 7pm. To learn more, visit events.teams.microsoft.com

UK's BSE risk status downgraded

The WOAH has downgraded the UK's international risk status for BSE to 'negligible'.

Defra says that the UK's improved risk status recognises the reputation for having the highest standards for biosecurity. It adds that it demonstrates decades of rigorous animal control.

Outbreaks of Bovine Spongiform Encephalopathy, also known as mad cow disease, have previously resulted in bans on Britain's beef exports.

The UK's new status could lead to expanded trade and better confidence in British beef.

Christine Middlemiss, the UK's chief veterinary officer, said: "WOAH's recognition of the UK as negligible risk for BSE is a significant milestone and is a testament to the UK's strong biosecurity measures and the hard work and vigilance of farmers and livestock keepers across the country who have all played their part in managing the spread of this disease.
