It’s not a breed, it’s a cross breed.
there are a lot of cons.
firstly if a puppy ends up with the worst traits of both breeds would you be ok with that? All cross breed puppies are different because some are more cocker, some poodle, and on a sliding scale between.
are you ok with the demands of grooming? They need combed through every day, they need very regular professional grooms. A lot of groomers hate them as it’s difficult to keep on top of, then they have to deal with the consequences. They aren’t hypoallergenic, and there’s a 75% chance they will shed.
lastly cross breeds are puppy farm/unethical breeders money makers. No breed checks for health, no limits on number of litters, they can just churn them out in a shed in the garden. You need to be extremely careful and really look in to where the puppies come from. Of course many people don’t care and are fine with puppy farms, but personally they wouldn’t be getting my money.
a decent breeder will have a wait list. If you can get a cockerpoo straight away chances are it’s not a decent breeder. My neighbour breeds, one litter every two years, two litter max per bitch. She has a waitlist and only has a litter when the waitlist is longer than 15, so every pup is guaranteed a good home. She barely makes any money with vet care etc.
