Froome's adverse analytical finding during Stage 20 of the Vuelta a España has sent the cycling world into a spin, with no ban yet to be announced for the four-time Tour de France winner.
His anti-doping sample was discovered to contain over two times the maximum allowed level of Salbutamol. He has admitted to using an inhaler containing the substance and still has the option to prove that the test result was due to physiological factors outside the norm.
Froome (Sky) is scheduled to ride both the Giro d'Italia and the Tour de France this season, with the prospect of a ban casting a shadow over the sport.
Fresh off his dominant performance to win the time trial by over a minute, Dennis (BMC) was asked about his potential Giro d'Italia rival and his opinion on the matter.
"I've made it no secret of mine that I've got no tolerance for any sort of positive test and that goes for myself as well," he said.
"If I accidentally or purposely take something, which I never would do purposely, then you just have to own it and accept that you'll get a slap on the wrist and try to move on, not make that mistake again."
Dennis also went on to suggest that he would have taken a different course of action to the current path of Froome.
"I don't know the full details, but for myself, if that was me I'd say 'I screwed up, I shouldn't have done this'," he said.
Former teammate and friend of Froome, Richie Porte (BMC) was reticent to pass judgement on the matter involving one of his main rivals for the Tour de France.
"When I heard the news I was in a massive shock, but let's see what happens," Porte said. "Let it all run its course. But I'm as flabbergasted as you guys are. I'd probably rather not say too much."
Froome is continuing to fight the charges and simultaneously prepare to race in 2018, race results that may be overturned if he is subsequently confirmed to have breached the anti-doping rules.
