Study challenges behavior myths around popular doodle crossbreeds

Some popular “designer” poodle-cross dogs may show more problem behaviors than at least one of their purebred parent breeds, according to a new Royal Veterinary College study published March 19 in PLOS One. In a survey of 9,402 UK dogs, researchers compared cockapoos, cavapoos, and labradoodles with their progenitor breeds using the C-BARQ behavior assessment and found that crossbreeds scored worse in 44.4% of behavior comparisons, versus 9.7% where they scored better and 45.8% with no meaningful difference. Cockapoos showed the broadest pattern of elevated undesirable behaviors, scoring worse than parent breeds in 16 of 24 comparisons, while cavapoos scored worse in 11 and labradoodles in five. Researchers and outside commentators said the findings challenge the common assumption that these dogs are automatically easier to train or better with children. (eurekalert.org)

Why it matters: For veterinary professionals, the study is less about blaming a breed label and more about resetting expectations. The authors and outside experts said behavior differences likely reflect a mix of genetics, breeding practices, early-life experience, socialization, and pet parent experience, not a simple “crossbreeds are worse” conclusion. That matters in exam rooms, because doodle-type dogs are often acquired on the promise of family friendliness, low shedding, and easy trainability. Prior RVC work also found these same designer crosses are not broadly healthier than their parent breeds, undercutting another common assumption and reinforcing the need for counseling that focuses on temperament, welfare, breeder quality, and realistic training needs.

What to watch: Expect follow-up discussion around breeder practices, early socialization, and whether behavior counseling for first-time pet parents should be more explicitly tailored to doodle demand and marketing claims. (smithsonianmag.com)
