Fraser sounds just like Louis, who is also 9 months and has the attention span of a gnat at the best of times. At training class it's often even worse than that, plus he's now started barking when we're in class. Our class is quite small, currently about 6 dogs, all of them entire males, and Louis is the youngest . It takes place in a fairly large hall and if Louis is becoming too hyper I take him to the far end of the hall for a couple of minutes and quietly work on my own, doing basics like sits, downs, stands and a bit of walking close to me, which gets his attention and calms him down.
With Louis, part of the problem is also frustration at being on lead and not being able to run about and use up his considerable energy. That's when the barking starts, so I'm clicking and rewarding when he stops barking for just a few seconds. It seems to be working.
He's just a teenager at the moment and although he gets plenty of free running in the New Forest every day it doesn't seem to blunt his energy and, of course, I still have to be mindful of how much exercise he has because of his age and physical development.
The training class is in 6 week blocks and I think when this 6 weeks ends I'm going to miss the following 6 weeks and do more training at home, plus maybe a couple of one to one sessions with my trainer. By the end of that he will be 11 months old and maybe a bit more settled.
