We have a multigenerational Australian Labradoodle:https://www.thelabradorsite.com/australian-labradoodle/ He rarely barks, has a a fleece vs wool coat (fleece is easier to maintain than a wool coat, which can mat more easily) and is a gentle guy. We have family members with asthma and allergies, so we really needed to get a dog that does not shed, and our breeder delivered. The standard Australian Labradoodle tops out at 65lbs or so but they do come in smaller sizes. If interested, here's a link to a list of reputable breeders:

Cavapoos and Shih-Poos are other smaller doodle mixes that are supposed to be among the calmest of doodles. Regardless of what type of dog you get, if you end up going down the breeder route, a reputable breeder should have an open house or opportunity to visit the facility in advance and should be able to explain what generation of dogs they are breeding -- F1, F2, or F3 / multigenerational. If you want consistency of traits, a F3/ multigenerational is the way to go. Good luck on your dog search. I hope you find a pet you like.
