There is a misconception in the UK that dogs are not allowed in
premises where food is served, such as restaurants and cafes. This
is not the case: the only legal obligation on the owner of such a
place is to make sure there is no risk of contamination and that
all food preparation areas are up to specified hygiene standards,
as set out in EU Regulation (EC) 852/2004, Annex II, applied in the
UK by the Food Hygiene Regulations 2006.
The Kennel Club actively encourages businesses, including those
which serve food, to become dog friendly as part of the club's Be
Dog Friendly campaign.
