Last spring, YouTube user 30poundman surprised his girlfriend with a new puppy.
The little pug was intended to help ease her broken heart: her 10-year-old beagle, B.B., had been put down earlier in the day due to a heart tumour.
"If there was a Geiger counter for adorable, it would be flying off the charts right about now!" wrote a CBS blogger.
"I am sitting here at work with tears in my eyes," one YouTube viewer commented. "What a sweet and wonderful thing to do."
"You never forget a friend lost, but taking care of a new one makes the sorrow a bit easier to bear. Thank you for sharing this moment with us," wrote another.
