Kean has insisted he will not resign, but Shearer admits it is a difficult state of affairs for the 44-year-old former Fulham, Real Socieded and Coventry assistant manager.
"The fans are unhappy and it is a tough situation for him to be in. They haven't got the points that everyone would have hoped," conceded Shearer, who scored 130 goals in 171 appearances for Rovers between 1992 and 1996, winning the Premier League in 1995.
Kean's reaction to Man City defeat
"He's having a tough time and he needs results ASAP, just like any other manager does. It's a tough situation and he needs to win games. He hasn't, which is why he is under pressure. He will have known that when he took the job though."
Shearer questioned the wisdom of such a trip considering their poor start to the campaign.
"I don't know what they are using it for, whether it is for a break or to play games or whatever but it is not ideal to be flying there when you are in their position and have got a free week without games [during the international break]," added Shearer.
"They would be better staying here to try to sort their problems out."
