I would honestly steer clear of poos, doodles, or any other designer cross.
Firstly it is very, very likely it will be puppy farmed or back yard breeder breeding these crosses for money. No health checks, unlimited litters per bitch- and these people can be very clever fooling you into thinking they’re genuine.
Secondly. With a cross you don't know which traits the dog will inherit. It may be a nightmare of a super intelligent poodle with endless energy and capacity for getting into trouble.
Speaking of- coat inheritence is unreliable too. Only 1 in 4 puppies will have the poodle like coat, the rest will have a mix or spaniel coat. You will need to comb (not brush) it properly and thoroughly every day, and grooming trips every 6 weeks. Neglect it and poo coats tend to “felt”, and the only way to fix it is to shear it all off.
If you need a hypoallergenic or non shedding coat, go straight for a poodle, or look at something like a yorkshire terrier. I always think this myth tha poo/doodles are hypoallergenic is dog homeopathy- take a poodle with a coat selected over many years to not shed and be less allergenic, and cross it with a normal, shedding dog, and somehow expect the puppies coats to be much less allergenic/shedding than the parent poodle 
Plus you will pay far more for a designer cross than you will a kc reg pedigree!
