Dogs are all over Shoreline and the only recomendation I have is if you have one - ensure that you ask others in elevators and common spaces before you enter with one as this is most often what gets complained about.
I recomend Blossom Village - Charlotte the director is great and the staff are warm and caring. I would recomend you take a look as it has a great space and is very flexible for working mummies. It is not British - but international, with qualified and caring people who go the extra mile. My ds is happy!
