We have tried the ignore technique, with no success. The dog just keeps on jumping...or will stop, but start again as soon as we turn around.

Both these dogs crave attention. We don't know Greta's circumstances at all, she was a shelter dog, but Cassisus came from an unloving, unhappy household where people were always screaming at each other. What an unhappy doggie he was when we first got him :-((. I considered it a personal victory the first time he wagged his tail :-)

I'm going to try body blocking, and see if that will do anything to stop them.

Thanks for your suggestion :-)
