i dont know keef,they had a yellow coat on over their bluey black u niform,so maybe they should be called the boys in the bluey black uniforms with bright yellow coats.
when i was buying my dog sign from Pets At Home,the man behind the counter said you have to display a sign regardless of what type you have, and that your dog has to have a contact number on its ID tg,regardless of micro chipping or its a £65 fine...dont know why though,i had zoned out by then
