Standard poodles take at least a full 2 years or more to mature. Donner stopped jumping (finally) when he was around 2. Time WILL improve things... your dog is still a puppy in his brain even if he is a full sized-dog. I know how hard this is... it is tough having a huge big goofball in the house. But he wants love. Try to give him 5 minutes of undivided attention several times a day: big dog hugs, petting, jumping, you make it... then stop. When he starts again, say "no, that's enough" and be firm. He will learn this phrase because he is smart. He just wants lots of love and reassurance, so give it to him, but then let him know that play is over for now. Good luck...
