Kane has started England's last two matches, even though his form for Spurs has been poor, and Dixon feels that his selection his justified.
The Arsenal defender says that the 22-year-old striker's presence makes him a variable option to the rest of England's forwards, and he believes that Roy Hodgson has to take him to Euro 2016.
"With Kane, you get something that no other player gives you," Dixon said. "He's taller and he's decent in the air. He also makes different runs to the other forwards in there. He's not the quickest, but if you get the ball into him in the middle, he can hold it up and bring others into play. We have nobody else like that."
Despite Dixon's glowing praise, Kane has scored just three times in 15 appearances this season for club and country, and he appears to be struggling to replicate last season's form.
The powerful forward netted 31 times during a wonderful breakthrough year last campaign, but he has slowed down considerably this time around.
Kane has looked off the pace for Spurs, and that may be due to the sheer volume of football that he has had to play recently.
Kane has shouldered a lot of responsibility for both Tottenham and England, but he will be hoping to show he can cope with those demands by getting back to his best form soon.
