Helping Sadie

About a year ago our beautiful Black Lab, Sadie, started showing symptoms of what we thought were allergies. After many Vet visits and even transferring her to another Veterinary Clinic we have come down to her needing to have a skin biopsy which requires anesthesia, surgery, and the biopsy sent to Cornell for analysis.  The cost of just the surgery part is $450. We do not have an estimate of the analysis by Cornell or what the treatment costs may be once we find out what is wrong with her. She has already gone through multiple steroid and antibiotic prescriptions, blood tests, etc. trying to treat her issues. She suffers every day with constant itching and chewing to the point of making her feet bleed and losing her fur.  We don't want to lose our baby and the joy she brings to us.  Please help us save Sadie.
