Henry is a working/show mix. On the down side he can be on the go all the time, especially afternoon/early evening. He has four walks a day, about 2/3 hrs all off lead. The upside is he never barks, is very friendly, clever, funny, shortish coat, easy to train. we wouldn't change henry for the world now, we are both much fitter
However, I think,if we'd have our time again, we may not have chosen him, because of his energy levels. And it is a lottery, you can get any character trait, and at a few weeks old the breeders cannot say your pup will take after the mum! We were told the same, we were also told he would just need two twenty mins walk a day and he slept all the time!
It's great you're doing your research.
