A major new UK study has found that some of the country’s most popular “designer” Poodle crosses may show more undesirable behaviours than their purebred parent breeds, challenging common beliefs that these dogs are naturally easier to train or better suited to family life.
Researchers compared behaviour scores for Cockapoos, Labradoodles and Cavapoos against their relevant progenitor breeds using owner questionnaires covering more than 9,400 dogs. Overall, the designer crossbreeds showed more undesirable behaviours than a parent breed in 44.4 per cent of comparisons, and fewer undesirable behaviours in just 9.7 per cent.
Cockapoos showed the most concerning profile, differing from Cocker Spaniels and Poodles in 16 out of 24 behavioural comparisons and scoring worse in all 16. Cavapoos also scored worse in most of their comparisons. Labradoodles showed a more mixed picture, with some results better and some worse than their parent breeds.
The researchers say the findings are important because many owners choose Poodle cross dogs believing they will be easy to manage, trainable and good with children, despite limited scientific evidence to support those assumptions. The study warns that mismatches between owner expectations and reality can affect welfare, increase the risk of relinquishment, and in some cases raise safety concerns.
The authors conclude that each designer crossbreed should be treated as an individual type rather than assuming all Poodle crosses will share the same behaviour traits. They also stress the importance of careful pre-purchase research and realistic expectations before bringing any puppy home.
