There is growing evidence supporting clinically important associations between age at neutering in bitches and subsequent urinary incontinence (UI), although much of this evidence to date is considered weak. Target trial emulation is an innovative approach in causal inference that has gained substantial attention in recent years, aiming to simulate a hypothetical randomised controlled trial by leveraging observational data. Using anonymised veterinary clinical data from the VetCompass Programme, this study applied the target trial emulation framework to determine whether later-age neutering (≥ 7 to ≤ 18 months) causes decreased odds of early-onset UI (diagnosed < 8.

Article Synopsis
  • The study uses target trial emulation to analyze veterinary data, focusing on the effects of surgical versus non-surgical management for cranial cruciate ligament (CCL) rupture in dogs.
  • It involved dogs aged 1.5 to 12 years diagnosed with unilateral CCL rupture in 2019, utilizing a framework to account for various factors that could influence outcomes, like age and comorbidities.
  • Results showed that surgical management significantly reduced short-term lameness by 25.7% compared to non-surgical treatments, providing insights into better treatment options for this condition.

Problem behaviours are a leading cause of relinquishment and euthanasia of young dogs. Previous research has identified associations between owner-reported problem behaviours and risk factors, including how dogs were acquired as puppies, early socialisation experiences, and owners' experience levels. Puppies acquired during the 2020 phase of the UK COVID-19 pandemic ("Pandemic Puppies") were more likely to be exposed to many of these risk factors compared to puppies acquired in 2019; however, consequences for their adult behaviour are, as yet, unexplored.

Target trial emulation applies design principles from randomised controlled trials to the analysis of observational data for causal inference and is increasingly used within human epidemiology. Veterinary electronic clinical records represent a potentially valuable source of information to estimate real-world causal effects for companion animal species. This study employed the target trial framework to evaluate the usefulness on veterinary observational data.

Article Synopsis
  • The COVID-19 pandemic sparked a significant increase in puppy purchases in the UK, known as the "Pandemic Puppy" phenomenon, but this surge often compromised canine welfare due to changes in buying practices.
  • Research comparing puppy purchase behaviors from 2019 to 2020 and into 2021 found that while many pandemic-related changes reverted to pre-pandemic norms, some, like video pre-purchase viewings and off-site puppy collection, persisted.
  • There was also a notable rise in puppies sold with passports, with over 10% of 2021 puppies having them, a significant increase since 2019, raising concerns about the legal age for import and the need for increased awareness and regulatory measures.
