Canterbury did it tougher than expected before consigning a spirited Newcastle side to their 14th straight defeat at Hunter Stadium.
There was nothing decisive about the 28-14 win but Knights coach Nathan Brown warned against writing off the Dogs come September.
"The Dogs are that type of team where they win lots of games like that," Brown said when asked if it was the performance of a genuine premiership contender.
"Once September comes - and getting in that top four is going to be crucial for all the sides - they have got a lot of big men and big men tend to help sides (win big matches).
"The last small side to win the comp was the Dragons five or six years ago but more often than not, sides with big people win and they have plenty of big people.
