We are going to have her checked again, it seams that this is the most likely cause. Since she was doing alot better before she went into heat, and she was on her heart worm then. So that fits also. We may take her to another vet just for the test, since I do not want my vet to think we do not believe him. He is great and we like him alot.
I would be afraid to start a treatment like that with out a vet knowledge. We would need to improve her protein level with this treatment correct?
