In the well at Tiddington Roman settlement (Warwickshire) - 2nd century AD ish - there were remains (several skulls/skeltons each) of two types of dog, one similar to Iron Age dogs as described by Harcourt and one with clearly slenderer skull & other measurements, probably also smaller so more like what you'd call a whippet nowadays. (I did the bones from this site many years ago and I don't think it has been published, but I have a record of the dog measurements if anyone's interested.) The two types are distinct, so in that sense you might argue that there were "breeds", but whether there is any relationship with modern breeds is debatable. I think it has often been noted that there's much more variability in Roman period dogs in Britain than in the Iron Age.
