Michael Vick -- Pumps Up Nate Dogg's Son

Michael Vick just made another deposit in the karma bank ... 'cause dude inspired a young dogg -- Nate Dogg's son -- by reaching out to talk football and family this week.

Here's how Vick connected with Naijiel Hale -- a football stud at Lakewood High, outside Los Angeles.

Naijiel's mom entered him in a Vick giveaway contest on Facebook by telling the Eagles QB ... her son is a huge fan of his, and "a sophomore starting DB (defensive back) with awesome grades :)"

Couple days later Vick personally responded with an email to Naiji, saying ... "Congratulations on a good season and thank you for the support." Naijiel told his hero, "Its been a hard year with my dad passing," and added he and Nate Dogg used to watch Vick play every game.

A rep tells TMZ, Vick decided to contact Naiji after reading about his H.S. football success -- leading the league in interceptions -- despite his father's death in March.

In his last email Vick said, "Sorry to hear about your father but glad to see you're being strong and keep achieving."
