The Leeds United winger has helped his nation to the European Champipnships next summer.
Northern Ireland are on their way to the European Championships in France next summer after securing a win against Greece earlier in the week. They romped to a 3-1 win against the former European Champions thanks to a brace from captain Steven Davis and a headed goal from Josh Magennis.
Dallas however is adamant that Northern Ireland will not be going to France to make up the numbers.
The winger has been talking to Sky Sports about their achievements - as they take on Finland later today hoping to secure top spot in their group ahead of Romania - and he is clearly buzzing about the opportunity to be playing in France.
"First and foremost to represent your country at any level is obviously a proud moment but to represent your country at a major tournament would be the pinnacle of your career.
"Hopefully we can go out on Sunday, finish on a high and top the group."
Leeds fans will have just one hope for Dallas. The winger and most of his team-mates have rightly celebrated the qualification and go into the Finland game a little bit out of nick, so Leeds fans will simply hope he can come through unscathed.
