What you can do is this, ladies:
Spread the word that a decent rescue will homecheck, assess, neuter, vaccinate, chip and be there to take the dog back throught his life.
Spread the word that not all rescue dogs are strays without history and that many come from family homes but in a decent rescue will be assessed regardless.
Offer to dog walk for local rescue - often the DC can join you!
Offer to help clean kennels
Offer to homecheck
Offer to transport a dog from, say, a home to the rescue if he is unwanted and needs to get from a to b - rescue will NOT ask you to carry a dangerous dog or take risks (they leave that to the experienced nutters in our midst!).
Offer to fundraise (NOT the RSPCA please, they already have 119 MILLION in the bank, local, non funded rescue needs it more than they do and picks up the dogs they reject!). You can do a car boot, ask local pet stores and supermarkets to donate spare food, help rescue if they have a stall at a fete, use artistic skills to design sponsorship forms and to follow up and send off sponsored dogs' photos and updates etc
Offer rescue your shredded paper, newspapers, blankets, duvets, washing powder, dishwasher tablets, dog toys.
Keep a penny jar and donate it to rescue
FOSTER... either for a rescue that doesn't have kennels or for one which does but needs space freed up and which has dogs which would really benefit from a home ebvironment. You can foster long or short term, might opt to train a puppy or take in an oldie, have a short coated dog which doesn't fare well in outside kennels in winter, a dog which is shortly to go into a home and needs a bit of reminding what one is, or for the more expperienced, take on a dog like my foster GSD, who has epilepsy or which needs assessing prior to rehoming, needs to be cat trained etc. Fostering is very flexible and each family and dog is placed according to ability compared with need, plus the rescue will pay all food bills and any necessary vet treatment.
