Is this the right breed name?

My boyfriend showed me a very lovely bunny at his place of work.
Knowing I am terrified of them because my previous bunny, a Rex, got very vicious he wanted me to try holding her and I fell in love.
The breeder who brought the rabbits said they were dwarf dutch lop eared rabbits.But I am having trouble finding information about them online.
She has the lop ears and long soft fur and is smaller sized like a dwarf. I really want to learn more before I decide to take her home and try again.
Also her fur is very matted and clotted up can I try to brush her or should I? Her temperament is very calm and quiet she just lets me hold and pet her and was very content.
Any ideas please?
