I would definitely be getting a second opinion. No pres diet.. talk with a nutritionist.. hate pres dog food. hate hate hate HATE it!!! it is not good for our babies. a nutrionist will help you!! please don't give up.
chasing geese??? hmmm. i can honestly say if you baby was that bad and was chasing geese? no- i won't believe she is that far into this disease unless she is sick. Sick and vomiting...
second opinion big time. I don't want to upset you bc there could be other issues going on here- but I think it would be definitely worth a second opinion. I sent you some links and they are LOADED with info on how to read labs and diets and all kinds of important things we need to know and try when dealing with kidney issues. I would also get on line and join this group. you have to set up an account (free) and also explain to them why you want to join. I am in the process of joining myself.
