Dog surgery

This sweet old gal is in need. Bailee was initially raised as a bird hunting dog. She was professionally trained, however the hunter ( the original owner ) decided she wasn't fast enough. She was put in a back yard and sold. Owner #2 found out she had glaucoma and had to have an eye removed. She wasn't good enough for hunting. Back to a back  yard.  It's a very long story, but I have rescued this sweet lady and she is spoiled rotten! She will never have to spend another night outside ever again! 

Recently, Bailee was diganosed with a rather large fatty tumor near her hind leg. It's been tested and is non-cancerous. The problem is that it is very uncomfortable for to rest or walk with. 

I am seekeing 600.00 to help me pay for this procedure. The whole price is 1200- I've been able to scrape up half.  Please help this sweet old lady enjoy the rest of her years pain free.
