Help with movie find

[WWII]

Can someone try to help me find the link that shows some working dogs. It has two dogs that play tug-o-war for like over an hour. It shows some hanging on a springpole, pulling weight. I think it took place overseas (not USA). Thanks

This might be it.

Yep, that would be it. Thank you so much.
