You are most welcome, glad I could be of some help, lol
If you can get a pick of him standing, like a body shot I could tell you, but he looks awesome to me, but exercise is always good, and I LOVE to see a nice lookin bully, one that is in shape and neat

The back pack is a great start, lots of walking, fetch springpole/flrtpole work, as well as treadmill, he will be a beast, not that he isn't, I mean that in a good way, lol. But being pure RE, he could be very well muscled if given the proper workout

I hope that makes snese, lol. We have an awesome Bully section further down on the forum, have a look around in there, ask any questions
