I have had four pups with PLE....Cookie is the best one for me to share in terms of treatment and it being documented here. What you are being advised diet wise is not something I have ever done or been advised to do. Not saying it is wrong...just isn't what I have done or would do. As mentioned above I sought out the counsel of vet nutritionists. Cookie lived a long life with PLE and what got her in the end was lymphoma. I posted that information above...the one link does emphasize the importance of a very balanced diet for this condition!
When Cookie had fluid unbalance, she was given hetastarch. I don't know why your Rosie's abdomen is swollen, but you might ask them to explain.
It is great that her numbers are up and yes, they do usually start backing off on rechecks....at first that was scary to me. I was ready to check all the time...I was so afraid she would go bad so believe me I get it!
Perhaps Cookie's story will help you.
