Kennel costs for your dogs... I'll talk to you later
Been thinking about this all day - really need to get out more.
Local newspapers was my first thought - with an appeal to sponsors. I know the Echo love a good sob story and a sob story with a dog is even better.
Pet food companies - I know Burns sponsor a lot of things. JWB and CSJ would be the other 2 that spring to mind.
Dogs Today - think they are the one with the coldwetnose blog. If you can get an appeal on there you might get some offers of sponsorship.
Local companies - years and years ago I needed funding to go to Hungary. We got quite a bit of money (in small amounts) by writing to local companies. Some only gave £50 but it all helped.
Organise some sort of evening event - particularly if you can blag a venue for free. Even something as simple as a quiz evening can bring in a few hundred quid. And you know what dog people are like for a good excuse for a drink
You will go to the ball (switching from the Wizard of Oz to Cinderella - though I still think you're more wicked witch than Cinders!)
I'll keep thinking... you'll probably smell the smoke from Newport!
