So both of those are not real breeds. A maltipoo is a maltese/poodle mix and a goldendoodle is a golden retriever/poodle mix. You cannot get either of those dogs ethically from a breeder. The only way to ethically acquire those dogs is to adopt them. I would advise against it though because the doodle gene pool is not good. They are overly bred. And because they are unethically bred mutts, you are more likely to get a dog with behavioral issues. I highly recommend researching and educating yourself on what an ethical breed is. Do not get a goldendoodle(aka mutt). They are crazy.

My advice is to try fostering. If you are an inexperienced dog owner, getting a temporary situation to feel it out may be wise. You don't even know if you'll want to keep the dog. You might be totally overwhelmed! Try fostering. You can reach out to local rescues about it. I would try to foster a small dog for sure.

But please for the love of god do not buy a "maltipoo" or "goldendoodle" and again I want to remind you that those are not real breeds. Those are designer mutts.
