Early neutering of bitches increases incontinence risk
Bitches of certain breeds are more prone to early-onset urinary incontinence
Research reveals link between age and onset

Urinary incontinence affects around three per cent of bitches in the UK. The condition can be distressing and costly for owners and also harm the welfare of affected dogs, owing to an increased risk of urinary infection and dermal lesions stemming from urine-soaked skin.

The link between urinary incontinence and neutering in bitches has previously been suspected, but a study published in the Journal of Small Animal Practice provides real evidence on the extent of this relationship.

The results identified an increased risk of 2.12 times of urinary incontinence in neutered bitches compared with entire individuals. Further to this, it identified an increased risk of 1.82 of urinary incontinence in bitches neutered before six months of age compared with those neutered from six to 12 months within the first two years following surgery.

Although there are many benefits to neutering bitches, these results will help veterinary professionals to make evidence-based recommendations on the timing of neutering, whilst taking other considerations into account.

Other key findings include:
  • average age at diagnosis of UI was 2.9 years
  • average time from neuter to UI was 1.9 years.
  • bitches weighing over 30kg had 2.62 times the risk of UI compared with bitches weighing under 10 kg
  • increasing bodyweight was also associated with an increased risk of early-onset urinary incontinence.
The study also indicates that bitches of certain breeds – Irish setters, Dalmatians, Hungarian vizslas, Dobermans and Weimaraners – are more prone to early-onset urinary incontinence than other breeds; which highlights that special care needs to be taken when deciding on whether to neuter these breeds.

The research was supported by BSAVA Petsavers and collected data from anonymised veterinary clinical records of 72,971 bitches.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

New guidance for antibiotic use in rabbits

New best practice guidance on the responsible use of antibiotics in rabbits has been published by the BSAVA in collaboration with the Rabbit Welfare Association & Fund (RWA&F).

The guidance is free and has been produced to help veterinary practitioners select the most appropriate antibiotic for rabbits. It covers active substance, dose and route of administration all of which are crucial factors when treating rabbits owing to the risk of enterotoxaemia.

For more information and to access the guide, visit the BSAVALibrary.
