Dex Lee (born 16 May 1993) is an English actor, known for his role as Bear Sylvester on the BBC soap opera Doctors.

[7] Steph Watkins of A Younger Theatre wrote: "Odyssey the dog, played by Dex Lee, is a highlight from the performance.

He carefully displays the naivety, purity and innocence of a dog whilst narrating incidents that take place without action; it is an effective story-telling tool as well as being one of the most memorable parts of the show due to how Lee handles the text.

[8][9][10] Bethany Davidson of A Younger Theatre described his performance as "insatiable, oozing confidence whilst he lolls and rolls around the room".

[11] Lee began filming on Doctors on 26 June 2019,[12] with his first on-screen appearance as Bear Sylvester airing on 18 November 2019.
