I'm not the one to critique, but coming from a show line lover, I wasn't too impressed. I tend to favor the german show lines more, but there are some american/canadian line dogs that I like too.
Something about that gate didn't seem right. Kind of like that video going around about pedigree dogs. This dog just seemed a little too much (half dog / half frog type thing going on) - didn't seem to really flow like a GSD should.
