The young Canberra native said he had worked on his running ability and body shape over a dedicated summer, and was in a good position to push for a senior game at some stage this season.
"Last year in the review, they said they'd look to give me a go depending on form," he told afl.com.au.
"I'm aiming to play anywhere between one to 10 games this year. If I get a game, that will be great, and if I don't, I know there's things to improve on."
The 19-year-old was sent away on holidays with the knowledge the coaches wanted more from him across the impending pre-season; namely in regards to running.
Tutt sat down with the club's head of physical conditioning Bill Davoren at the end of last season and devised a plan to boost his endurance levels.
With a cross-training program containing interval training, fartlek running and bike work, Tutt managed to achieve the goal of pushing into the top 10 runners at the club.
"I haven't been the fittest bloke but I worked on it a fair bit. I've always had a bit of an endurance base but I haven't been at the top of the ranks," he said.
"Last year I was in the higher of two groups of running but I was towards the back, and now this year I've moved up towards the front.
"I put on a little bit of extra size as well, which is what they wanted me to do, so it's been pretty tough but I've got through it."
Tutt was so dedicated to the program, he embarked on the Dogs' end of season trip to Hong Kong and then came straight back to Australia.
He also moved in with Liam Jones and enrolled in a Bachelor of Applied Science course at Victoria University over the off-season with an eventual aim of becoming a PE teacher.
His football schedule will allow just one subject to be undertaken this year, which is sports psychology.
"It's something that can help me out with my footy because there is a focus on mental toughness," he said.
"We have the Bulldogs Academy [run by Peter German and Chris Maple] at the club for first and second year players, which is just like a way to fast-track your development.
"The leadership group come in and have talks to us about their expectations, and teach us about mental toughness.
"It really helped me out last year. Now we're reading [former Test cricketer] Justin Langer's book and it's all really helping."
Tutt played one NAB Challenge game - the Dogs' big win over Fremantle in Bunbury - and stood out with two goals.
He said his role would change this year based on which team he was playing for, and subsequently would continue to train with both the midfield and the backline.
"I think more at Williamstown I'll be more on the wing to use my endurance there, to run and carry the footy," he said.
"I tend to do a fair bit more stuff down back at the Bulldogs. I'm just working more on my defensive game because I'm quite strong at tackling but defensively I need to improve."
