Dummett, who joined United as a nine-year-old, has now made more than 130 appearances for his boyhood club - and Taylor knows just what it takes to go from a wide-eyed Academy prospect to a Premier League regular.
"I still speak to him regularly and I think he's done magnificent," Taylor, now 32 and with Peterborough United, told nufc.co.uk.
"I don't think he gets the credit he actually deserves. He played some fantastic games last year after coming back from a big injury, and it seems to go under the radar for a lot of people.
"But it's great to see him doing well. He's secured a long-term contract, which he fully deserves, and I wish him all the best for the rest of his career. Hopefully he can stay here for as long as I did."
