Our White German Shepherd, Caesar enjoys his run about in our large but steep back garden. He found one of his favourite balls (we hide them as he will nag all day for it to be thrown and will then tease us with it placing it on our hands without actually letting it go and then run away with it!). The cold weather doesn't put him off either!
All with Nikon D800 and Nikkor 24 - 70 at f/6.3
70mm 1/2000 ISO 500 (forgot it was still on ISO 500 from shooting a few days ago)
Nice set of shots. Especially like the first kitchen shot. His fur looks like you could ruffle it. Image has an HDR look to it. The ones in the garden with a shallow dof are also nice, though try to leave a little more room in front of him. The ball shot - Caesar and his ball-4 is just right.
