The dehydration would have quite an effect on poor Peanut...I know you aren't in the desert yet, but is it quite a bit dryer in your RV, or in the area where you are now?

I hope the fluids really make a difference. Does she eat wet food, and did the vet recommend adding a bit of water to it?

Poor girl - I hope the new AB and fluids do the trick!

HUGS to you and Terry - you just may have your girl for a good while yet, without the peeing!
