My son and his friend wanted to know what they could do to help and my eldest daughter came up with a few ideas,
Call some of the schools and ask if they would sell our pens and pencils at the reception area,
do a greyhound and lurcher awareness day at their schools,
everyone loves a puppy so why not get a male, female and a puppy to stand at the school gates and do a pet corner, all the parents will be there and the kids will all want one . 
I know a few managers at asda, from hamilton to grangemouth, why dont we ask them if we can stand at the door with collecting cans and donating mandate forms??????? has to be worth a try.
