Surgery for Wolfe

Wolfe has a blocked salivary duct which is causing him discomfort as the salivary gland in his neck swells and fills with sticky think saliva. We have had the gland drained 4 times now. We took him to a veterinary surgeon and were advised that the salivary duct should be removed. Draining repeatedly can lead to infection.
We then received the total cost of the surgery......$2,200 and an additional $250 if he stays overnight.  
Unfortunately this is more than we can afford. We both applied for Care credit and were denied???
If you can help we will be forever grateful

Thank you so much.
