I have seen rescues that limit themselves to toy dogs or small breeds. But I don't believe I've ever seen a weight restriction as a way of controlling intake. Area? Yes. Or perhaps need? Yes. Strays only? Yes. But never weight. You can always say "No, but I can refer you to XYZ rescue".
I've been in and around shelters and rescue for many, many years. The tiny ones always find wonderful homes very easy. At least if they are healthy. The tiny sick ones often require thousands of dollars of care. And the others you may come accross can be extremely behavioral because of past experiences...that means months in rehabilitation and dealing with a possibly nasty dog until things change. As far as volunteers in the fields where you need them, medical, they need to be skilled and available and willing to abide by your tiny dog policy as well. Many that will donate time will feel it unethical to discriminate that way. And volunteer foster homes around the country would require you to approve them, check on them and them to have access to funds and veteranary services to care for these babies.

There is a TON to deal with. I can go on and on. Seriously, if you feel you have the time and energy and desire, channel it towards volunteering at a shelter that cares for cats, dogs, birds, mice...everything.

Even volunteering can take a tremendous amount of love and time and patience.
