Labradoodle & Goldendoodle Forum
I think I can answer your questions in one sentence: Your mom should get a Standard Poodle.
If you consider the fact that there is not one single doodle breeder in North America who has ever put an obedience title on any of her dogs, despite the fact that the AKC does allow mixed breeds in obedience competition, you will understand the reason for my answer.
She should also search Petfinder.com at least twice a week (doodles in rescue are in great demand), using Standard Poodle as the breed, as there is no "doodle" option.
I am sure your mom knows how to find an excellent Poodle breeder. The local AKC regional breed clubs are a good place to start.
A word of warning: Most purebred Lab, Golden, and Poodle breeders of good quality and reputation take a very dim view of breeding doodles, so expect some negative if not outright hostile feedback if you mention LDs or GDs to these breeders.
I think that line of questioning will get you better responses, lol.
Although the difference between a Golden Retriever and a Chesapeake Bay Retriever in terms of temperament is like the difference between a house cat and a Cougar, lol. I'd stick with why Labs over Goldens, or vice versa. :)
Karen has given you excellent information. My son purchased a poodle puppy last year from a reputable breeder. I am totally in love with that dog and she with me. She has a wonderful temperament and is well behaved, however she has excitement pee. They come over often and we always clean up pee - we all hoped she would outgrow it but she hasn't.
I adore my doodles. One I purchased as a puppy from a breeder. He is more independent and isn't snuggly. I have two rescue doodles, both rescued at age two. Both are wonderful dogs, the newest one, is pretty high energy still, barks, and humps other dogs when meeting them for the first time - things we might have worked on more easily if we had gotten him as a puppy. He also runs when you go to discipline him - obviously learned that worked in his previous living situation. His favorite place is on the couch with us with his head and paw on a lap. He is the absolute expectation of what a doodle's personality is characterized to be.
We used to have a Springer Spaniel who was so high energy that it made me tired. He had separation anxiety, was nervous, and was the sweetest, most unassuming dog that you could take anywhere and count on him to be friendly and non-aggressive. He was from a backyard breeder.
I mentioned these things because they are dog things and not breed things. Some I think are the result of poor breeding, and some are just individual personalities.
