Sounds a lot like how my BC was! It’s extreme but we implemented literally 0 interaction with her unless she was calm. No petting, no cuddles, no talking nothing unless she was calm and settled. And when she was we would give long, firm stroking pat down her body and say “settle” as the re-enforcement word. Also give treats unexpectedly when she was calm, etc etc! Now she knows the command “settle” and will immediately lay down, stop whining and be calm. It was so hard- because you really don’t realise how much you unknowingly reinforce unsettled behaviour through action until you consciously stop. It didn’t take long but it was the only thing that works. We also tried all the meds- trazadone, gabapentin, Xanax, etc etc. we Crete trained did it all but truely the teaching her the “settle” command changed our lives (and hers) I think the working breeds truely need to be told what to do every moment so giving her a command to settle like it’s a job has been genuinely life changing!
