We've had diplodog for around 6 months now and it's been a bit or an uphill struggle due to her anxiety, although she has a lovely nature and is slowly improving. One thing that isn't improving, and is actually getting worse is that she keeps jumping up at the table when people are eating, and will even take a quick bite if she can manage it. She also keeps trying to sit on the sofa, which we don't allow. We normally crate her during mealtimes, but ideally would like not to have to. We are completely consistent and never let her put her paws on our laps or the chair - we say "off" and avoid eye contact when we're sitting at the table. She's a bright dog - she picks up commands really easily at dog training and runs through them beautifully in the comfort of her own home (although outside is another issue due to her nervousness) but "no" and "off" seem to be beyond her. Any ideas? Is it just stubornness?
