I just double checked his pics... adn he somehow reminds me of Glacier´s Ozzy and/or Mac...

could be an Alaskan Husky mix...... look at those legs!!.... and now he doesn´t seem to have that large chest as a sighthoung may have....but then again he could be a race line Alaskan husky/lab mix and still be lean...

and in this pics you can clearly see some huskyish mask...
