I am no help here! My first thought was 'good luck with that.' Tee hee! I do not mean that ugly in any way, but in a humorous way. We have the HARDEST time getting onto Katie Scarlett! She is just so dang cute, it is all we can do not to smile or giggle at her wacky antics. But I do know that some of their antics (such as the potty pad chewing) can be very frustrating. We tried the squirt bottle, she thought I was playing. I tried shaking the can of coins...worked for about a week. I tried shaking a jar of marbles...worked a few times. I try stern 'no' or 'eh eh' and sometimes it will work. We are working on 'leave it' command now. It's a work in progress. Our trainer at class taught us this. Also when I tell her to leave it or get onto her, I (try) to make stern contact with her with my eyes. I stare at her and she stares right back. I do not look away until she does. I read somewhere that when they look away, in doggy speak, they are submitting to you. So that seems to help a little with us. But for us, I guess I am a softie and I overlook a lot of Katie Scarlett's uh-oh's. We are not strict disciplinarians with her. She pretty much does her own thing most of the time, but she knows what she can and can't do. She will test you, but again, I do the eye thing or 'time out' and she immediately quietens down. Being just me and my hubby, no skin kids, this works for us. And I know many do not agree with time out, but it works for us. Katie Scarlett knows exactly what the words 'time out' mean. I can ask her, do you want time out, when she is doing something she shouldn't, and she immediately quietens down and is good. For us, time out is where I place her in her crate for a minute or two, no longer than 3 minutes. I don't put any toys or anything in there with her. And she figured out quick what time out was. Now I rarely have to put her in time out. She knows when Mommy means business.
Good luck!
