As usual, I am late to comment...I saw this yesterday offline but now when I came back, it wasn't there anymore...Kim I am sorry but though this shot is very nice indeed, it lacks the real action of the other one that has the dog growling. Beautiful rendering though and good composition. Your subjects are nice and beautiful but my best favourite is still the other one with the full teeth showing...
Point is, I like your dog and handler shots -- Each one has their own merits, so please do not give up submitting these. I had always look forward to them, perhaps others too. I don't find them boring..and this is only my opinion.
