The Clarets boss felt his side were worthy of their eighth win in 11 games, courtesy of Gray’s 12th minute penalty and a stunning second two minutes before the break.
And the gaffer praised his fearless striker, who took his personal tally to five in as many games to follow up his double against Bolton last Turf Moor last time out.
Dyche said: “Credit to Huddersfield because they came to play, but I felt we dealt with them well overall, other than the last five minutes following a breakaway goal.
“Before that, we had enough chances and scored two good goals. The first, from the penalty, came from a great move form Tom Heaton and them not touching the ball.
“The second was a similar thing, with great link play between the two strikers to get in behind and it’s a sublime finish.
“Andre has that edge about him where he has no fear. If he misses, so what, and I tell him that I’m not bothered, so long as he’s in there to score… and he’s certainly doing that.
“As the Championship does, it throws up an interesting last five minutes, and then they are putting the ball into the box, but I felt we dealt with it well in the end and ran out worthy winners.”
Dyche, who received a cake from the Board of Directors on the eve of the game to mark his third anniversary, joked: “I was expecting a Rolex, but in these parts you tend to find they don’t do stuff like that!
“I got a cake though, so I was buzzing off that and I thank them for it.
“I did think there might be a Rolex in there, but when I put the knife in, it was just sultanas. Maybe another day…”
Reflecting on his reign, which sees him now the 13rth longest serving manager in English football, he added: “It’s certainly gone quick in my mind, but long in the world of management.
“I believe I’m flirting around the top 12 of managers in the entire league now, which is an achievement in itself given the demands.
“But the main work has been done by my staff and the players, all the different players my three years, the board and also the fans.
“After a tough first six months for me, they have really taken to me and what we are as a team. That connection is strong and long may that continue.”
