Felipe literally gave the shirt off his back to warm up a cold dog! Gabriel later wrote the video going viral surprised him, and he's glad he decided to share it with the world.

"I rarely post anything to my feed, but it deserves to be shared."

Watch the incredibly sweet moment below:

When the brothers returned to that same station on the way back, they looked for the dog Felipe outfitted. They hoped they might take the pup home with them, but he was no longer there.

Felipe later shared online that though the t-shirt was a favorite of his, it looks better on the dog.

"There is no way to change the world — but for the things in your reach, you can."

The way I see it, one small change in the world still makes a change in the world. It takes a truly kind person to give something away to someone without, even if that someone is a dog. Commenters on the video agree.

I'll make sure to layer up in the future, just in case I pass any strays who might need an article of clothing.
