Truly a beautiful set of images, in the first 2 of the dog's eyes seem very sweet and quiet motion, in the third accounted for the dog seems much more "mischievous".
Then in what follows the first but shows a different character, of course I assume they were playing.
Instead it captures well the last all that these fellows can donate to us men who unfortunately often not reciprocated.
Technically, all the pictures are well executed.
