Nothing can stand in the way of this dog-and-baby friendship

Meeting a friendly dog who loves to play fetch is one of the greatest joys of life. And if your new furry friend is determined to let you into his life despite the metre-high fence that keeps the two of you apart, then the chances of your bond lasting a lifetime are even higher.

This is what Twitter user @CMNelsonPhoto discovered when he walked out into his backyard and saw his two-year-old son tossing a ball over the fence.

The young boy, noticing the dog, walks up to the fence and throws the ball over. The dog, clearly eager for a bit of play time, picks the ball up and drops it back over the fence. 

The game carries on over the barrier like this, resembling something more like a tennis match than an average round of fetch. 

But the two will not be deterred: a fence means nothing when you've got a tennis ball and the desire to build a new relationship. People who saw the little boy's unconventional game of fetch thought that the display was truly heartwarming.
