What else is wrong with Stormy? I read the part about her not having a nose because of chemical burns, a broken rib?, LP and a lump in her neck? I also read where you had another puppy before Stormy who died? Thats awful-what happened? Just curious if she suffers anymore health problems or had other accidents that add to her vet bills & health problems?
I think the vet prob. thinks your in over your head and is just wanting to help. I have never heard of an abusive vet or a vet with cruel intentions..I think you should give him the benefit of doubt and talk to him. Maybe he'll have more compassion and offer some assistance at a reduced fee to help Stormy. There is no telling what happened after you left-or what their intentions were.
No doubt you've been through a lot and love Stormy. Your doing the right thing by weighing your options.
Go talk to him when you feel a little bit better, thinking clearer and see what he can do to help.
