Excellent work, author!
Edit: SBS would have been even better.

There is really nothing extraordinary done here. All color images were changed to black and white. I used layer mask's for the blending process. Each dog's face layer, has been blurred slightly and a levels adjustment layer clipped to it. The background of the motorcycle source picture I did not like. So I adjusted it's levels, enlarged, put a slight motion blur to it and placed the forest scene on bottom layer and masked out the parts of motorcycle layer not needed (layer Mask again.) The finished image was saved then reopened and copied. To the new copy I used the Pixelate>Pontillize filter at level 3. Lowered the opacity of that layer some and set blend to darken. As a final step I placed and adjustment layer for solid color sepia. I'm glad you like it, thanks.

'prociate it Nator yeah I do.

LOL, these pups are really on the job, they look so serious - great finds. Nice technique to make this look like an old shot, author. Glad to see the paw replacing a hand on the rear dog. Love the goggles and hat on the Shepherd, really fits him.

Lovely image, good work author!

great job here also, fits the mood very well and looks like it belongs. well done.
