Crossbreed Dogs Display Higher Rates of Behavioural Issues, Study Finds
In a surprising revelation for dog lovers across the UK, a new study has indicated that popular crossbreed dogs, including cockapoos and cavapoos, may exhibit more behavioural problems than the pure breeds from which they are derived. The research, published in the journal Plos One, analysed data from thousands of dogs and suggests that these designer mixes could be prone to issues such as aggression and fear-related behaviours.
Rising Popularity of Poodle Crossbreeds
The UK has seen a significant increase in the popularity of poodle crossbreeds, often referred to as "doodles." This trend is largely driven by the perception that these dogs are hypoallergenic, healthy, and excellent with children. However, the study's findings challenge these assumptions, highlighting potential drawbacks in their behavioural profiles.
Researchers from the Royal Veterinary College conducted an extensive analysis using data collected from 3,424 crossbreed and 5,978 purebred dogs. Owners completed an online questionnaire that covered various aspects, including their expectations, training methods, and detailed behavioural assessments of their pets.
Detailed Behavioural Comparisons
The study evaluated dogs on 12 different behaviour scales, revealing stark contrasts between crossbreeds and pure breeds. Cockapoos, a mix of cocker spaniels and poodles, scored worse than poodles on six scales, showing higher levels of owner-directed aggression, stranger-directed aggression, dog rivalry, non-social fear, separation-related problems, and excitability.
When compared to cocker spaniels, cockapoos also displayed more undesirable behaviours in areas such as dog-directed aggression, stranger-directed fear, dog-directed fear, and trainability. Similarly, cavapoos, crosses between cavalier king charles spaniels and poodles, performed worse than cavalier king charles spaniels on eight out of nine scales where differences were noted.
Labradoodles, another popular crossbreed, showed mixed results. They scored better than poodles on six scales but worse than labradors on five scales, indicating variability in behavioural outcomes depending on the comparison breed.
Expert Insights and Environmental Factors
Professor Daniel Mills, a veterinary behavioural medicine expert at the University of Lincoln, commented on the study, noting that while it provides valuable insights, it does not imply that crossbreeds are genetically predisposed to behavioural issues. He emphasised that behaviour results from a complex interaction between genetics and environment.
"Behaviour is always the product of the interaction of genes with the environment, and looking for simple causes in one or the other is doomed to failure," Mills stated. He also pointed out that cultural factors, such as owner expectations and training practices, could play a significant role in shaping these behaviours.
The study underscores the importance of thorough pre-purchase research for potential dog owners. By understanding the characteristics of different breeds and crossbreeds, individuals can make more informed decisions and better prepare for the responsibilities of pet ownership.
Future Research Directions
Mills suggested that further studies are needed to explore the causal factors behind these behavioural differences. Tracking dogs and their owners over time could help disentangle the influences of genetics, environment, and owner behaviour, providing a clearer picture of what drives these issues.
This research serves as a crucial reminder for prospective pet owners to look beyond trends and consider the full spectrum of a dog's needs and traits. As the popularity of crossbreeds continues to grow, such studies are essential for promoting responsible pet ownership and ensuring the well-being of these beloved animals.
