I'm so sorry, Karen, that you're faced with such a difficult decision. Out of all the members here, I felt that you and I were the most similar in terms of our beliefs in rawfeeding and following a holistic / homeopathic, chemical-free upbringing.
But for Annie's sake, I'd like to suggest to please try a different route. I remember when I first brought home Stig, he developed allergies right away. His hotspot and hives were out of control. He had scabs all over, all the hair on his wrinkles fell off, he really looked like a sick puppy. Went to the vets almost every week, spent thousands of dollars, and still they couldn't give me answers. It didn't occur to me to try a different route until we hit bottom, which is when my bf and I decided to give it a couple of weeks, and if he didn't improve, we'd give him back to the breeder.
It was then when I researched for options, and found this site. I wouldn't have tried raw if it wasn't for one of the members suggesting it. I wouldn't have known to look for a different vet, if it wasn't recommended here. And from there, I continued to meet numerous people who promoted natural remedies.
I guess what I'm trying to say is that, there's never only one way of doing things. A couple of my close friends had to give her bully steroid shots, one lived to be 13 years old. Sarah, Lisa's first bully, is allergic to 20 foods, and double that for environment, and another double if she travel to another state. She's 10 years old now and still loving life.
I'm not saying that steroids is the answer. Only to please exhaust all the options. I know you're at your darkest at the moment and feel overwhelmed with sadness and anger, maybe even tired, but please give it another thought. Stig wouldn't be with us now if it weren't for people sharing their perspectives and experiences, even if they sound foolish and irrational at first.
