Cockapoo, Cavapoo and Labradoodle: What UK Research Reveals

They look like soft toys, are widely seen as ideal family pets and are promoted online as perfect “all-in-one dogs”. However, research from the United Kingdom casts serious doubt on the reputation of these fashionable crossbreeds. Rather than being consistently easy-going and friendly, many display more behavioural difficulties than their pedigree parent breeds.

What the researchers examined

A team from the Royal Veterinary College in the United Kingdom analysed data from 9,402 dogs. The sample included three particularly sought-after crossbreeds:

• Cockapoo: Poodle × English Cocker Spaniel
• Cavapoo: Poodle × Cavalier King Charles Spaniel
• Labradoodle: Poodle × Labrador Retriever

Every owner completed the standardised C-BARQ questionnaire. Used internationally, this tool makes canine behaviour measurable. It covers 24 separate areas, including:

• aggression towards owners
• aggression towards strangers
• fear of other dogs
• a tendency towards nervousness and overreaction
• difficulties being left alone

The researchers then compared each designer crossbreed with both of its parent breeds. For every individual behaviour, they assessed whether the crossbreed performed better, worse or roughly the same.

Result: In almost half of the comparisons, the fashionable crossbreeds appeared to show more behavioural issues than the breeds involved themselves.

How often fashionable crossbreeds perform worse

The findings are clear. In 44.4 per cent of all comparisons, the crossbreeds recorded less favourable scores than their parent breeds. They appeared behaviourally superior in only 9.7 per cent of cases. In around 46 per cent, there was no clear difference.

This challenges a widespread assumption: many buyers believe that combining two “nice” breeds will automatically produce an even more balanced dog. The data point more towards the opposite - at least for some of these designer dogs.

The Cockapoo stands out most negatively

Most concerningly, the Cockapoo - a favourite among many influencers and families - fares worst in the comparisons.

• In 16 of 24 behavioural areas, it appeared more problematic than its parent breeds.
• These included aggression towards its own owner, increased aggression towards strangers and pronounced oversensitivity.

The Cavapoo also shows notable weaknesses. In 11 of 24 traits, it appears more challenging than the Poodle and Cavalier King Charles Spaniel. The most striking issues are:

• separation anxiety, meaning stress and panic when left alone
• insecurity and fear when interacting with other dogs

Many of these dogs look friendly and cuddly - but internally they are more often struggling with fear, nervousness and stress.

Labradoodle results are more mixed

The Labradoodle comes out somewhat better. It ranks behind its parent breeds in five areas, but exceeds them in six other behavioural measures.

For example, the Labradoodle appears to be:

• less aggressive towards its owner than the purebred Poodle
• less aggressive towards other dogs than the Poodle

This demonstrates that crossbreeds are neither automatically a risk nor a miracle solution. Each mix brings its own combination of strengths and weaknesses. Even within the same crossbreed, individual bloodlines and breeding programmes can vary greatly.

A billion-dollar market built on myths

The popularity of these dogs is largely driven by expectations that have little scientific support. Online and among many breeders, claims such as these are common:

• “easier to train”
• “almost allergy-free”
• “perfect for children”

The study now assessed finds no robust evidence for these hopes. Even so, the market generates enormous sums. Estimates put annual revenue connected with Doodle and Poo crossbreeds at more than one billion dollars.

Marketing promotes trouble-free family dogs - but the data instead show more fear, more stress and more frequent behavioural concerns.

What this means for future dog owners

The researchers call for buyers to be given much more honest information. Anyone choosing a dog solely on appearance and popularity risks becoming overwhelmed later on. If an animal’s temperament does not suit an owner’s lifestyle and experience, the risk increases of:

• frustrated owners
• surrender to an animal shelter
• behavioural problems caused by ongoing stress

A dog whose needs and temperament are misunderstood is more likely to show fear, restlessness or defensive behaviour. This applies to crossbreeds as much as pedigree dogs - but with heavily promoted fashionable mixes, the idealised image and reality clash particularly often.

Not a “bad dog” - but often the wrong expectations

The study explicitly stresses that designer crossbreeds are not inherently “bad” or “difficult”. Many live peacefully with families, and some are genuinely dream dogs. The issue lies more in the image used to market them.

Anyone acquiring such a dog should understand that:

• the crossbreed may inherit problematic traits from both breeds
• individual puppies within one litter can have very different temperaments
• training, suitable activity and the environment shape behaviour at least as strongly as genes

A highly nervous Cockapoo needs different strategies from a laid-back Labrador. Ignoring that can quickly lead to a lasting conflict with your own dog.

What the terms mean

Designer dog - what does it actually mean?

A designer dog is not a fashion accessory, but a deliberately planned cross between two specific breeds. The aim is often to combine supposed advantages from both parents - for instance, the supposedly “allergy-friendly” Poodle with the “family dog” Labrador.

In practice, though, these pairings do not create predictable “dream combinations”; they are genetic lottery tickets. Every mating reshuffles inherited traits. Even siblings can respond entirely differently to noise, children or unfamiliar dogs.

Why Poodle crosses are so fashionable

Poodles are considered highly intelligent and shed less than many other breeds. This gave rise to the idea of crossing them with popular family dogs to produce an “easy-care all-rounder”. According to the British study, that formula does not automatically work.

If a highly sensitive Poodle is paired with a nervous Spaniel, the result may be a dog that overreacts to every small thing. Good marketing cannot replace sound data - let alone careful selection of responsible breeding programmes.

How prospective owners can make better choices

Anyone considering a Labradoodle, Cockapoo or Cavapoo should take several points especially seriously:

• Assess the breeding establishment critically: How do the parent dogs live? Do they appear relaxed and emotionally stable?
• Ask for full information: Reputable breeders speak openly about potential challenges associated with the crossbreed.
• Review your own day-to-day reality: Do I have time for training, activities and periods of rest?
• Consider alternatives: Many pedigree dogs and rescue crossbreeds are also excellent fits for families.

Those who honestly consider their own limits and research thoroughly greatly improve their chances of building a stable, long-term human-dog partnership - regardless of whether they eventually bring home a Labradoodle, a Cockapoo or an unassuming rescue crossbreed from an animal shelter.
