Hi my name is lucy.. Just joined… I was hoping someone out there can help me. I just adopted a english bull dog. She is 7months old. I was feeding her Origen for puppies. I took her in to my vet for her preop for spaying. Her blood test came high in phosphous, so he took a urine test. Everything was clear. My Vet is saying that it might be the food.. To get some food low in Phosphorous. I have done extensive research. Hard to find this because most of the foods say .9 min.. how do i know the max.. The only food that said max 1.0 is wellness core. the two foods that look good to me is the wellness core for puppies and the natures variety raw food chicken meal.. please help….
