Weimaraners bit by Snakes/Need Vet!

URGENT: Our 2 Weimaraner puppies/dogs (10 months and 16 months) were bit by what appears to be a rattlesnake and are in bad shape. We are in dire financial straits already due to a layoff and desperate to save our dogs. Our vet at Animal Health Services in Cave Creek, AZ recommended this as a way to help raise the funds needed for our dogs to receive the anti-venin treatments & hospitalizations needed to save their lives.  Please if you can help us do !!
