Dean, who plays Robbie Jackson, appeared on the ITV daytime show with Robbie's new dog Wellard 2, the second version of his beloved companion Wellard.
Wellard 2's real name is Panther, and Dean said: "I think it's the grandson of the original Wellard. It's the same family, the same breed.
"There were so many names. I think they had a fun day at the EastEnders headquarters thinking of a new name, and I think in the end somebody just said, 'Look, let's call it Wellard 2.'"
The pair posed for photos outside the ITV studios ahead of Dean's chat on the show where he talked about his return to the soap. Dean has recently reprised his role as Robbie for a brief stint to tie in with Carol Jackson's exit storyline.
Robbie was last seen on our screens in February 2010 when he walked Bianca down the aisle at her wedding, and fans were ecstatic after seeing him make his return to Albert Square last week.
