That's brilliant to hear Mark, baby steps, yeah, but in the right direction. I'm just going to throw this into the mix, what does she eat ? Bear is just over 9 months and he's fairly big, (63lbs at last weigh in) and he was a right git when we were out, pulling, mouthing, jumping. Then, after reading on her about raw diets I changed him over and the difference is stunning, instead of pulling constantly now it's only with reason ( pidgeon ! Cat ! Mum I need a tree ! ) he only jumps t certain people now and the mouthing is a good 80% less. Yes it could be he's simply growing up and the training is starting to kick in, but such a drastic change in a month ? It might help jazz as well, there are some threads here, have a read
