A woman was on vacation in Mexico when she spotted a heartwarming scene of an unlikely friendship building. There was a small white dog that was climbing a wall and searching for something on the other side. And then, a large German Shepherd came into view and she understood what was happening.

Despite being separated by a very tall wall, these two neighborly dogs were forming an unlikely friendship. The dogs then appeared to jump up onto the fence to hug each other and greet one another. Scaling the fence was no easy task for either dog, but they seemed up for the challenge to build their friendship.

Watch the video to see how sweet this friendship is.

No fence could keep them apart.
