Some advice about Della?

[morethanpretty]

She will not quit itching herself. The worse part is where she keeps biting the same part on her leg, its starting to lose hair and is red. She started this in September I think. I gave her kid's benedryl (which is what the vet recommended) but it didn't seem to help much. So, per the vet again, I switched to zyrtec but it seems to help even less. The vet said I would need to bring her in for a steroid shot if it continued, but because of my recent health/insurance misfortune its kinda a stretch for me to afford. I will if I have to, but does anyone else have any advice? Its mainly that 1 place she keeps biting, could it be a "hot spot" or is there an oil/lotion that might help?
Apparently she was biting it a lot last night, it looked pretty bad this morning . I'm gonna have to do something else soon.
