My sister-in-law, Laura, has a purebred female GSD, Eva, who is just a little over one year old. Eva is very intelligent, loving dog, but has some behavioural issues. The one that is most distressing to those around her is her tendency to jump.
We've tried every technique we can think of. Ignoring, as is recommended on your site, worked for Laura when Eva was younger (and smaller), but does not work for anyone else in the family now that she's a full-grown dog. Eva has developed the bad habit of jumping on you from behind now if you ignore her. She even pulls hair and nips now.
We know it all stems from a dominance issue; Eva has an extremely strong ball drive, and is telling us, who she sees as below her in the pack, that she wants us to play. The pack basically goes: Laura, Eva, Maggie and Annie (the other two dogs), and then everyone else.
Is there anything you can recommend? We've tried ignoring, bringing up our knees, doing the "Cha-cha" (holding paws and walking her a step or two back), and clicker training with rewards when she has four on the floor. We've gotten desperate enough to try "nipping" her chest with our fingers when she jumps, and stepping on her back toes, but even these techniques do not work with her, despite working with other dogs in the past.
It was suggested that my in-laws try putting her on a leash, and when someone comes in the door to put the leash under their feet so she can't possibly jump. There are two problems with this: 1) Eva doesn't just jump when people come in, and 2) there are two other extra-large dogs that will drag her around by her neck if a leash is attached at all times.
To make matters worse, her jumping was rewarded when she was a puppy by certain members of the family, because they thought it was cute. They even tried to differentiate between good jumping and bad jumping, the first being when Eva was asked to come "up," and the latter was the rest of the time. I'm sure it confused her to no end. Any help or extra references would be greatly appreciated!
Thank you so much for your time. Kind regards, Natalie
