As Jane said, poodles don't shed, and they're considered hypoallergenic. Service dog orgs started this trend because they were trying to improve the service dog stock. They were hoping to cross Labs and poodles (and Goldens and poodles) and get service dog prospects with the best of both breeds (particularly non-shedding and hypoallergenic). Admirable, but it didn't work the way they'd hoped.
Unfortunately, the crosses tend to be terribly cute, which pet owners like. The big issue I have, though, is that the breeders promote the crosses as hypoallergenic and non-shedding, neither of which tends to be true. I worry that people with allergies will take a chance on a pup and then dump it at the shelter because it makes their home life miserable.
I don't have such a big issue with the "idea" of a doodle cross. God didn't make dogs -- Man did. We did so intentionally, by identifying a need and selectively breeding for it. What need are the doodle crosses filling? Cute, family-friendly pets -- which I'd hazard as guess is the most-common "job" of an American dog in this day and age.
