My 11-month-old goldendoodle jumps on everyone who visits. I've tried having guests ignore her but she just keeps jumping until they give in. It's out of contro

Ignoring doesn't work if guests eventually pet her. She learned that jumping 15 times gets the reward on attempt 16. That's intermittent reinforcement — the strongest kind. You need active consequences, not passive ignoring. Put her on a leash when guests arrive. The moment her paws leave the ground, turn and walk her into another room or outside. Wait 10 seconds. Return to the guest. If she jumps again, remove her again. Repeat until she keeps four paws on the floor for 5 seconds, then let the guest greet her. Most doodles need 6-10 cycles before they stop offering the jump. This only works if you control the interaction with the leash — if she's loose, you can't enforce the consequence fast enough. After three weeks of consistent practice with 8-10 different visitors, she'll generalize the rule. If you only practice when your mom visits, it'll take six months. You need reps with different people in different contexts. Set up fake visitors if you have to.
