Help for stray dogs

Have family of 3puppies and a mum on our land the mum and daughter of which need veterinary treatment and we have been unable to get them help as all the kennels are full and we don't have the funds to get them vet treatment. Would try to get them into the car and take them anywhere should anyone be able to offer assistance. The mums face ears and tail have sores and the daughter showing signs too and we also have a dog ourselves that we worry could get infected.
