Kuldeep, who is expected to play a vital role in India's World Cup campaign in England, said that former Indian captain, who is known decisive and accurate decision behind the stumps, sometimes goes wrong.
"There are a lot of times he (Dhoni) goes wrong but then you can't say that to him," Kuldeep joked during an award show on Monday.
Kuldeep also said that Dhoni speaks after the end of an over only if it is required.
"He doesn't speak much. He speaks only between overs if he thinks he needs to point out something," added Kuldeep.
Dhoni, the skipper of Chennai team, became the most successful wicket-keeper in the history of IPL by taking his dismissals tally to 132.
Lately, CSK spinner Imran Tahir praised Dhoni after achieving career-best 4 for 27 against KKR during an IPL league match.
The 40-year-old Tahir gave credit to Dhoni for his splendid bowling and also said that MSD is helping him a lot.
