It probably is big dog what?
Good relationship being felt, it is good atmosphere.

What I imagine in Poland is Pomeranian and a Polish Lowland Sheepdog.
But, this footprint is like a one of the bigger dog.
I am convinced that the dog is the best friend for human.
Thank you very much!

Is it a dog and a footprint of a walk?
An idea is good!
Thank you for comment to a photograph of a river.
